    Postfix on Centos(Virtualmin) goes to Spam - Multipart Messages

    Hi guys

    I'm new here and I'm sure this question has been thrown around a lot but I just couldn't find a solution. I have a networking website I've setup and we need to send notification mails to our members depending on activity related to their profiles(messages, comments etc).

    We are hosting the site on Centos5.6 with VirtualMin and are using Postfix as our MTA. We also use google apps for email on the site. Heres the problem, the mails go through for some gmail users but more often than not, they end up in gmail,hotmail and yahoo spam.

    We've setup the appropriate SPF codes on the server, DKIM and rDNS works fine.

    v=spf1 ip4:xx.xx.xx.xx a mx include:_spf.google.com ~all

    Below is a sample email that goes directly into gmail spam. I've replaced the actual values with dummy text (Ip, Domain etc)

    TBH, this kind of thing is nigh-impossible to remotely troubleshoot when you're removed/munged all the relevant bits.

    That being said, I'd look at your hostname and PTR records, as those are the usual places that people screw up. (And takes, like, ten seconds to check... when you've included the actual FQDN and IP addresses.)

    (Another possible option may be that you have no CAPTCHA or other security measures on your signup form, so you're getting lots of bogus accounts from spambots using fake gmail/hotmail/yahoo addresses, and actually are, from their perspective, spamming them.)

    Oh, it's almost certainly unrelated, but your SPF record is almost certainly grossly redundant, and definitely less-than-useful. ("~all" should really be "-all".)

    We've tried two options of the SPF records(only one at a time)
    v=spf1 ip4:xx.xx.xx.xx a mx include:_spf.google.com ~all
    and
    v=spf1 ip4:xx.xx.xx.xx a ~all

    Both fail. Even tried removing google apps from the picture all together. Didn't work.

    Isn't using -all wrong?

    Would this be a more accurate SPF?
    v=spf1 a aerver.domainxyz.com ip4:xx.xx.xx.xx include:_spf.google.com ~all

    or
    v=spf1 a aerver.domainxyz.com ip4:xx.xx.xx.xx include:_spf.google.com -all
