Gmail mark messages from my mail-server as spam

goshanecr · Jun 11, 2011

Hi friends!

I have a mail server: FreeBSD 8.2_x64 + Postfix + Dovecot + MySQL. My domain is prem-ekb.ru. DNS-related stuff ise OK (A, MX, PTR, SPF), I checked my IP and domain at MXToolBox, Spamhaus and various others which I couldn find. How can I solve that problem?

Original mail headers:

Code:

Received-SPF: pass (google.com: domain of gosha@prem-ekb.ru designates 94.31.161.3 as permitted sender) client-ip=94.31.161.3;
