here are the headers of the blocked messages (actual domain replaced with domain.com, ip address with n.n.n.n and gmail account name with person.account):

Messages go to Spam folder on various gmail accounts, so it's not a coincidence.

I followed all gmail guides on sending bulk emails from here https://mail.google.com/support/bin/answer.py?hl=en&answer=81126. I also checked my ip-address here http://www.dnsblcheck.co.uk/ and it's NOT on the blacklists.

Thus I have two questions:

  1. What may be the possible reason for the messages to go to Spam folder?
  2. Is there any way to contact Google and ask them what causes this?

Update: I have set up openDKIM on my server, everything works, gmail message headers say that dkim=pass, which means everything is set up correctly. Messages still end up in Spam folder.
