    I was notified by Comcast that I need to make changes to the way I send
    email via their servers. The changes required a port change and start
    using username and password. To test that this works I used Thunderbird
    and set the following:

    Server Name: smtp.comcast.net

    Port: 587

    Use name and password are checked and the User Name box contains my user

    Use secure connection: No

    Using these setting I am able to send emails via their servers but
    obviously this is not what I want to do, this was just testing that
    these settings are valid.

    I then changed my main.cf to have the following lines:


    smtp_sasl_auth_enable = yes
    smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
    smtp_sasl_security_options =

    In sasl_passwd I entered the following information:

    smtp.comcast.net my_user_name:my_password

    did a postmap on the file to create sasl_passwd.db and reloaded the
    configuration using postfix reload.

    When I try to send an email via my server I find the following in the log:

    May 10 15:15:11 coral postfix/qmgr[4449]: 73A64F64001:
    from=<>, size=1117, nrcpt=1 (queue active)
    May 10 15:15:11 coral postfix/smtp[6660]: connect to
    smtp.comcast.net[]: Connection refused (port 587)
    May 10 15:15:11 coral postfix/smtp[6660]: 73A64F64001:

    dsn=4.4.1, status=deferred (connect to smtp.comcast.net[]:
    Connection refused)

    At this point I am not sure where to go from here.

    Using telnet I can see the following:

    avi at minnow:~$ telnet smtp.comcast.net 587
    Connected to smtp.g.comcast.net.
    Escape character is '^]'.
