I've set up my own server and I'm really struggling to stop any outgoing email go to spam.

I've used allaboutspam and mail-tester.com to test it and they both come back with perfect results. No issues with reverse lookup, dkim or spf records. As far as I'm aware, I'm not on any black lists.

Below is the SPF record I'm using. The record name is cornhillfarm.co.uk

v=spf1 ip4:95.138.166.68 +a +mx ~all

Here's a brief clip of the header sent to gmail from the account

Any ideas on what I've done wrong here to try and get it out of the spam folder?

If you need any other information about my setup that I've missed, let me know and I'll send the relevant information.

Thanks in advance!

  • Are you saying Google marked this as spam despite the "Received-SPF: pass" results? Or am I misunderstanding the question? Remember, Google filters spam on content as well as headers/source.

  • That's correct, Google is still marking it as spam. I've tried different subjects and messages and it's still appearing to be filtered into spam. Any ideas?

    @EEAA Not a duplicate of that question; it deals with incoming spam. Dec 1, 2014 at 20:20
  • @MichaelHampton as far as I see, the given header is from a mail sended by grid3.woodbridgemedia.co.uk sent to gmail.

I went through and looked for obvious DNS issues and none were apparent. As far as I can tell it's an issue of IP reputation.

There are really only two good solutions to this:

  1. Get added to mail server whitelists and/or warm up the address by putting legitimate traffic over it.

  2. Use a smarthost/relay like Mandrill or Sendgrid. They're dirt cheap and make it easy to get past even the most stringent spam filters.

I'd recommend option 2 over option 1 for a SMB or similar.
