iredmail - all test scores are perfect - mail still goes to spam

Hi everyone

time ago, i installed iredmail to my 1gb(ram) droplet which runs with ubuntu.

fqdn,rdns, dkim keys(multiple domains) set correctly (I asume).

before, my mails go to inbox directly but now they go to spam folder.

Here are some test results (which are perfect)

• http://www.mail-tester.com/web-PmzGFH

• http://www.allaboutspam.com/email-server-test-report/?key=0779FB454E5DF652ACF63A3C5A70CBC9

also,

I dont have any significant errors in mail log. But I got this time to time :

NOTICE: reconnecting in response to: err=2006, HY000, DBD::mysql::st execute failed: MySQL server has gone away at (eval 136) line 170, <GEN34> line 2776.

What could be the problem? Everything seems correct but still mails go to spam…

I am wondering 1gb memory is enough or not. However ı dont want to pay +$10 before it is certain…

Many thanks
