It seems I have a mail problem…

December 12, 2007 | Computers

Huh. I’ve got comments here I never got notification emails for. There’s no mail error logs on the server. I have no mail notifications in my mailbox, and no records of those emails in my spam filter.

It would seem they just vanished into thin air…

  • Sadly, it is still mysteriously broken…

  • Hm, it seems that dynamic IP blocks from Comcast are automatically on SPAM watchlists. So my server’s emails were being denied from my email box.

    I’ve gotten service back by telling my server to use the SMTP server provided by comcast, but they’re getting flagged as spam. Well, at least they’re coming through…

  • Okay, so, a little research told me that I had to properly relay through comcast. Several posts told me that I needed to use port 587 but those actually failed, but defaulting to port 25 works.

    I had to make some modifications to postfix.

    In /etc/postfix/main.cf

    relayhost = smtp.comcast.net
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_security_options =
    smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

    I then had to create /etc/postfix/sasl_passwd and add

    smtp.comcast.net myusername:mypassword

    Then get postfix to regenerate the password hashes and refresh

    myserver:/etc/postfix# postmap sasl_passwd
    myserver:/etc/postfix# postfix reload

    The last part was not obvious to me and took a while to find, but I eventually found it… lucky me, eh? So, now between that and a whitelist on my hosts email config I get comment notifications again.
