    Comcast Customers: Comcast has been somewhat randomly blocking port 25 (the outgoing mail SMTP port) for many of its subscribers claiming anti-spam measures. Once they block port 25, your outgoing email will no longer be sent out - it will typically get stuck in your outbox and you may or may not see an error message when trying to send. Don't bother to request that Comcast unblock port 25 - they won't do it.

    The work-around recommended by Comcast is to setup your email client to use an alternate port. Comcast provides port 587 as an alternate and Point B Web has also made port 587 available for outgoing mail. We also recommend that you use Comcast's SMTP services on port 587 for outgoing mail (instead of your own domain / our server). There is a KB article related to this here. The configuration instructions below also show the setup for using Comcast for outgoing mail.

    Outlook 2003 Configuration for using port 587 for outgoing mail

    These instructions are for Outlook 2003, but other versions of Outlook and Outlook Express are very similar. First, go to the Tools menu and select "E-mail Accounts"

    Choose "View or change existing e-mail accounts" and click Next...

    Select your Default account from the list and click Change...

    Your Incoming (POP3) server information should be set to your domain hosted by Point B Web. The logon info on the screen above refers to your incoming (Point B Web hosted domain) mail server which is your email address and password.

    *Note: You can also use it for outgoing, but as mentioned, we recommend using your Comcast account for outgoing.

    Click the More Settings button...

    Click the Outgoing Server tab and set it up as indicated above with your Comcast user login and password.

    *Note: If you do use your own domain for outgoing mail, you can choose the option to use the same settings as incoming.

    Now click the Advanced tab...

    This is where you enter the alternate SMTP port as indicated above. Enter 587 and click OK...

    Now you can click the Test Account Settings button to make sure everything is working. Then click Next and finish the setup. You are now good to go.
