    Mail delivery failures from Comcast

    Anyone else have issues with people sending emails from Comcast?
    My anti-spam system flags them as spam and bounces their emails.
    While the content looks harmless, I'm guessing something amiss
    in the headers.

    So my response to GofBorg's comment is...

    Might be something with their email gateway(s)......

    I've had users complain of problems sending TO comcast from our domain.
    According to comcast, our mail server was blacklisted somewhere. I
    checked everything I usually check, not blacklisted.

    So I filled out comcast's online form to get our domain IP removed from
    their blacklist, got a reply back that we were not blacklisted. All of
    a sudden we could email comcast again, with nothing changed on this end.

    Sending to I can somewhat understand, but my SPAM system blocks their users
    sending to us. LOL.

    Weird. I have not heard from anyone about incoming not working.
    Sometimes I hate email. <G>

    Well, here's the thing. It's pretty isolated to one user, a guy
    in marketing. He receives all manner of spammy looking sales guy type
    emails, you know the ones loaded with links to Facebook, Twitter etc,
    with logos and lots of html. Overall I don't have many email issues, but
    this one user is a chronic issue, either he can't receive or he can't send,
    or he can't view an attachment or his mailbox is full, etc. Problems and
    urgency increase at the end of each month.

    So my initial guess is something's up w/ his account or something. We
    run Groupwise here & I *have* had sporadic calls from users about not
    being able to receive emails from such & such, etc.

    More times than not when I get looking into it, they've enabled junk
    mail handling in their client and blocked an address or something. One
    time even a user had put an entire email domain (msn.com I think) in
    their local blocked list........sigh
