I have problem with delivering mails to GMail from a new server setup with configured exim4.
Messages sometime passed to gmail spam folder. But sometimes it rejects immediatelly. I have attached a success of incoming message to gmail.
Here is message source: http://dpaste.com/0KT384Z
I have tried disable ipv6 in exim4 without socuces. GMail already have in logs my pubic IPv6.
BUT. I have a right PTR and SPF records which shows in source as PASS.
I have no any ideas where I can get a help. I have used a google support page for get a support from google. but no any answers got in 10 days…
I dont know what I can todo. Can anyone helps me?
Source of returned mail http://dpaste.com/3STSAMW.txt , here also is a reason why it’s returned. The DMARC, SPF, and PTRs of my server IP is normal and displayed in delivered emails as PASS. Here is a test result from mail-tester.com: https://www.mail-tester.com/test-uyg3k
Haha, I think any message with the subject Привет is a bit suspicious!
But seriously, here is the relevant bit of the SMTP failure:
