    Configuring your new Exchange 2003 server for internet email with POPcon for downloading the email

    from POP3 mailboxes isn't hard if you just do it step by step as shown in this configuration sample. In this

    guide we will step through a sample installation of Exchange 2003 for a company we will call

    "Mycompany". Mycompany consequently owns the internet domain name "mycompany.com".

    Actually it only takes these simple steps:

    1. Adding your internet domain name to the recipient policies2. Configuring the SMTP server for inbound email3. Adding a SMTP Connector for outbound emails4.

    Configuring the email addresses of your users5. Installing and configuring POPcon, Exchange POP3 Connector

    6. (Optional) Check out the ChangeSender Exchange Send-as Outlook Add-inAnd this is how to configure the Exchange Server to accept email for a domain like "mycompany.com" and

    cooperate with POPcon:

    First install the Exchange server software from the CD or DVD. You may have to go back to the

    "Add/remove Software" utility in the control panel to add NNTP support if you did not do so during initial

    setup of your windows installation. Then open the Exchange System Manager and configure the newExchange installation.

    1. Adding your internet domain name to the recipient policies

    Open the Exchange System-Manager. It should look like this:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    2/33

    One of the problems most often encountered when configuring an Exchange 2003 Server system is the fact

    that often the internet domain name you want to receive email for ("mycompany.com") does not match your

    standard active directory domain name (i.e. "servername.mycompany.com"). The Exchange 2003 Server

    component handling incoming emails - the SMTP server - does not accept emails for other domains than the

    ones entered in the "recipient policies", even if you entered the correct email addresses

    ("[email protected]") in the active directory.

    To make Exchange accept email for additional domains like your internet domain you need to add the

    domain names to the default recipient policy like this:

    On the main tree panel of the Exchange system manager expand the tree "Recipients" and then click on

    "Recipient Policies". The policies will be shown on the right panel. Normally only the "Default Policy" will

    be there:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    3/33

    Open the properties of the "Default Policy" by double-clicking it:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    4/33

    In the Default Policy Properties please choose the tab "E-Mail Addresses". There you will find a list of

    domains supported by your exchange server. Usually only your internal active directory server domain will

    be listed here:

    Like you can see, after installing our Exchange Server from scratch only our AD domain "Christensen.local"

    was listed as accepted SMTP address. But emails from the internet will be coming in addressed to

    "@mycompany.com" and not Christensen.local!

    Choose "New..." here to add another accepted inbound domain. Since emails on the internet are sent via the

    SMTP protocol we want to add an "SMTP Address":

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    5/33

    Now enter the domain name you want to receive email for. Please add a leading "@" to the domain name.

    This is what we entered to support emails addressed to @mycompany.com:

    This is how the Default Policy Properties look like after entering the additional SMTP domain:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    6/33

    Enable the newly created entry with a check mark next to it:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    7/33

    When you OK the above dialog, Exchange will ask you with the next dialog box if you want to add the new

    address to all new users. Usually you do want exactly that to save some typing later.

    Please note: You may need to restart your server to activate the new domain!

    2. Configuring the SMTP server for inbound email

    Next we will configure the SMTP-Server. This is the part of Exchange that accepts incoming emails from

    POPcon. No special settings are needed to work with POPcon but these are the standard settings in any case:

    You will find the settings for the SMTP server under Servers/Protocols/SMTP/Default SMTP Virtual

    Server. Open the properties by right-clicking on the Default SMTP Virtual Server and choosing

    "Properties":

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    8/33

    The settings on tab "General" can normally be left to the defaults.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    9/33

    On the tab "Access" you can find some configuration settings that might interfere with POPcon.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    10/33

    POPcon only works with a standard SMTP connection WITHOUT authentication, so allow "Anonymous

    access" in the "Authentication" dialog:

    Choose "Connection" to grant or refuse the right to connect to the SMTP server to individual or multiple IP

    Address Ranges. Please ensure the system that runs POPcon does have the right to connect granted. With

    this setting ALL systems will have access to your SMTP server:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    11/33

    Under "Relay..." you can assign the right to relay through your SMTP-Server to some systems. This might

    be needed in some configuration and to be sure you should grant the system POPcon runs on relay rights.

    All other systems will need to authenticate before accessing the SMTP server to prevent unauthorized users

    using your system to relay spam:

    Under the "Messages" tab you can restrict message size and number of messages accepted for each

    connection. Please make sure these settings are liberal enough to allow POPcon to transmit large messages

    to your server.

    Also, on this tab you can choose an internal additional recipient for copies of the non-delivery reports. These

    NDRs will be sent back to senders of mails addressed to recipients unknown in your Exchange Server and

    they include a copy of the original message sent. You can use these postmaster copies of the NDRs to

    manually forward emails sent to mistyped recipients to the correct users.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    12/33

    Under tab "Delivery" some more configuration settings for outgoing emails can be found:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    13/33

    3. Adding the SMTP Connector for outbound emails

    Now we need to add an SMTP-Connector (vs. SMTP Server) to handle outgoing email to the Internet.

    Right-click "Connectors" in the Exchange System Manager and choose "New", "SMTP-Connector" to start

    adding the new connector and name it appropriately (like "SMTP-Out" in our case):

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    14/33

    On the "General" tab you can now choose wether Exchange will send outgoing emails directly to the

    recipients system ("Use DNS...") or if all emails should be relayes through a SMTP relay server ("smart

    host").

    The first option, DNS, is more direct but can sometimes cause problems when you use a dialup internet

    connection because some recipient systems will not accept emails that are coming from your ISP's dialup IP

    range while pretending to come from your real internet domain. Sending via your ISP's smart host / smtp

    relay server is the better option in this case. We choose our ISPs smtp relay server here.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    15/33

    Also, on this tab you need to add the "local bridgehead" server (as shown above)

    On the tab "Address Space" we need to add a wildcard address space for SMTP. We want to allow emails to

    any domain, so we use the wildcard "*" here:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    16/33

    Side note about the "Cost" entry: If you want to send emails to some domains via a different route you cancreate multiple SMTP connectors and set the "Cost" entry of this wildcard connector to a higher value while

    setting the cost entry of the special domain route to a lower cost but with only the special domain allowed on

    this page. This is especially useful if you generally want to send via DNS and only route to some systems

    that won't accept your email via some relay server.

    If your ISP's SMTP server requires authentication (and almost all of them do today) you can set the

    username and password on the "Advanced" tab of the SMTP connector. Select "Outbound Security":

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    17/33

    Select "Basic authentication" and chose "Modify" to enter the username and password:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    18/33

    And that's already it - Your Exchange is now configured to send email to the internet and receive an SMTP

    email feed like it will come from POPcon or a direct internet connection. All you should do now is configure

    your users' email addresses in the Active directory.

    4. Configuring your users' email addresses in the Active Directory

    You can set one or multiple email addresses for each user to receive email at. We will step through the

    necessary actions when creating a new user called John Galt.

    First open the active directory and right-click the "Users" item to select "New", "User":

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    19/33

    The resulting dialog will allow you to create a new AD user to log into your server and creates an Exchange

    mailbox all in one wizard pass:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    20/33

    Next...

    Next...

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    21/33

    Now the wizard continues into the Exchange Server realm and lets us create a new exchange mailbox

    We just accepted the default alias here. Next...

    Ok, fine - but wait: What about our desired email address? [email protected]? We need to add this

    mail address manually. We are back at the AD configuration console and select the properties of our new

    user "John Galt" by right-clicking on the name:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    22/33

    Lots of tabs on this resulting dialog:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    23/33

    We go to the "E-mail Addresses" tab:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    24/33

    And surprise: [email protected] is already there, but in suspiciously non-bold print. Actually,Exchange automatically entered this additional email address because we chose so during the editing of the

    default recipient policies. But we want this address to be the primary address meaning all email sent by John

    will get this address as the "senders" and "reply" addresses in the mail headers. So we click on "Set As

    Primary" and are done:

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    25/33

    We could also add more email addresses like [email protected] or [email protected] but onlyone of these addresses can be the primary address that will be the default senders' address in all emails sent

    out by John.

    And that's really it - just step through your other user's AD entries and set the appropriate primary and

    additional email addresses.

    5. Installing and configuring POPcon or POPcon PRO

    After going through the above 4 steps your Exchange is configured to send out email but it still can't pull

    down email from POP3 or IMAP mailboxes on your provider server. For this you need to install and

    configure POPcon.

    Configuring POPcon is quite straightforward. You need to follow these steps:

    a) Configure a Postmaster email address on the GENERAL configuration tab.

    b) Add one or more POP3 mailboxes on the POP3/IMAP tab.

    c) Configure the Exchange server name on the EXCHANGE configuration tab.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    26/33

    Download and run the self-extracting installer ofPOPconorPOPcon PROand follow the instructions

    during the installation. It will install the POPcon Administrator program and the POPcon service that runs in

    the background on your system.

    Run POPcon Adminstrator from Start > Programs > POPcon

    POPcon Screenshot

    Click on "Configure" to open up the POPcon configuration screen.

    a) Configure a Postmaster email address on the GENERAL configuration tab.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    27/33

    On this first configuration page you only need to enter the email address of your Postmaster or

    Administrator user. The Postmaster will receive all emails without a valid recipient as well as general

    POPcon status notifications. It is very important to define a real email address from inside your exchange

    server here because mails can be lost irretrievably if POPcon forwards some mail with no recipient

    information to the postmaster and that account does not exist in your exchange server.

    You can leave the log file options to their default settings for now.

    Next go to the POP3/IMAP tab to configure the POP3 or IMAP mailbox accounts you want POPcon to

    download email from.

    b) Add one or more POP3 mailboxes on the POP3/IMAP tab.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    28/33

    POPcon PRO collects mail from as many POP3 accounts you like. Just click on Add to add another POP3

    host or account to the list of Polled POP3 Hosts. For each server or account you need to fill in the POP3

    server settings as shown below.

    If you are using catch-all style mailboxes (mailboxes that receive email for a whole domain, regardless of

    the recipient part before the "@") POPcon needs to filter recipients from incoming mail so only the

    recipients at your own internet domain are accepted. Please add the domain you consider your own in the

    "Accepted Recipient Domains" box. This is the same domain you configured earlier in the Exchange Default

    Policy.

    Individual accounts settings

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    29/33

    This dialog lets you input the specifics about a POP3 or an IMAP server you want to have polled by POPcon

    PRO.

    This is the information POPcon PRO needs to know about each server:

    Server type:

    Here you can select on the four supported server types:

    POP3: Default. POP3 servers are by far the most common mail server types on the internet.

    POP3-SSL: Some POP3 Servers need SSL encryption enabled for the connection in order to protect

    passwords and sensitive information. Choose this type to have a SSL-encrypted connection to a POP3

    server.

    IMAP: IMAP Servers are also quite common and theoretically allow the client to manipulate email folders

    and move email between folders online. In our case the protocol is used to download email from the INBOX

    of the IMAP server to your exchange server.

    IMAP-SSL: Supports SSL connections to IMAP servers for added protection.

    Access:

    Configure the server name, account name and password to connect to the mail server here.

    Servername: The name the server you want to have polled. You can also enter the IP address directly.

    Username: The username needed to log into your POP3 or IMAP mail server.

    Password: The password needed to log into your mail server.

    http://www.servolutions.com/images/popconpop3s.gif
  • 8/3/2019 Exchange 2003 Configuration Step by Step

    30/33

    IP portnumber: Almost always the TCP/IP port for POP3 mail is 110. Under some circumstances, internet

    routers or firewalls change the port number. Please ask your network administrator or internet provider. The

    standard port for POP3-SSL is 995, for IMAP it is 143 and for IMAP-SSL this should be set to 993.

    Timeout: Leave this to the default value.

    Please ask your POP3 mailbox hosting provider if you do not have the above information.

    Type of mailbox / distribution:

    POPcon PRO supports both catch-all and single user mailboxes

    Catch-all mailbox ("*@domainname.com"): For this type of mailbox, POPcon PRO will distribute the

    emails retrieved from this server according to what it finds in the TO:, CC:, BCC: and other header-fields of

    the mail. If you choose this option, dont forget to add your internet domain name(s) to the "Accepted

    Recipient Domains" box on the POP3/IMAP configuration dialog

    Single user mailbox ("[email protected]"): This type of mailbox receives email for only one

    specific Exchange mailbox. You need to specify the receiver of the email here. POPcon PRO will then direct

    all mail retrieved from this server to the recipient email address given here.

    Delete / Keep email on the server:

    This block allows you to configure POPcon PRO to either delete email after downloading or keep it on your

    POP3 or IMAP server for a specified amount of time or indefinitely.

    Delete downloaded email: This is the default settingPOPcon PRO will delete the Email on your POP3 or

    IMAP server after successfully downloading it.

    Leave a copy of downloaded email (indefinitely): This option will cause POPcon PRO to leave a copy of

    the email on the server. Only use this option during testing or when you are sure the mail will be deleted

    eventually, i.e. by another system periodically downloading and deleting email.

    Leave a copy of downloaded email for n number of days: Causes POPcon PRO to leave a copy of the

    email on the POP3/IMAP server for the specified number of days before deleting it. You can use this option

    to allow access to a single POP3 or IMAP mailbox by two different systems.

    c) Configure the Exchange server name on the EXCHANGE configuration tab.

  • 8/3/2019 Exchange 2003 Configuration Step by Step

    31/33

    On this configuration screen you can specify the Exchange-(SMTP) Server you want the mail to be

    directed to. Normally this will be the computer name of your Exchange server (like "MYSERVER").

    You can leave all other settings default

    These three steps to configure POPcon will provide you with a working set-up. Test it out by confirming the

    new configuration with OK and then use the "Trigger mail retrieval" button on the POPcon Administrator

    main screen to start the first mail download. You can follow what is happening in the scrolling log display

    on that screen. Watch out for any error messages there. There is also a POPcon log file (c:\program

    files\POPcon\POPconSrv.logopen with notepad) that you can view at your leisure.

    6. Check out the ChangeSender Outlook Add-in

    ChangeSender Exchange Send-as Add-inadds one important piece of functionality to Microsoft Outlookwhen used with Exchange Server: It allows you to send as any of your email addresses and even group

    addresses or those of other users if allowed by the administrator. Effectively this is the Exchange Send-as

    function without the limitations of the ActiveDirectory

    http://www.servolutions.com/changesender.htmhttp://www.servolutions.com/changesender.htmhttp://www.servolutions.com/changesender.htm
  • 8/3/2019 Exchange 2003 Configuration Step by Step

    32/33

    Without the ChangeSender Exchange send-as component, Exchange always sends out emails on your

    default email address fixed in the ActiveDirectory even when answering emails received on one of your

    additional email addresses. Also, Exchange does not allow sharing the same email address (i.e. department-

    wide or company-wide email addresses) between users. ChangeSender solves both problems by adding a

    configurable "send as" selection box to your Outlook email form.

    ChangeSender Features

    Automatically selects the right send-as address when replying to emails. ChangeSender uses theaddress of the original email as sender address for replies.

    Easy selection ofsend as addresses for new emails via a new sender address selection box inOutlook.

    Multiple users can send from the same sender address (i.e. send as [email protected] [email protected])

    Sender appearance fully configurable as "Any name" for each individual emailaddress. Does not show up as "sent on behalf of...".

    Very simple installation and administration.

    Administrator can restrict or allow user choices for the sender address and prevent users fromsending as other users.

    Works with Exchange 2010, 2007, 2003, 2000 and with Outlook 2010, 2007, 2003, 2002, 2000versions.
