Hello guys,

It seems that I don't have SASL support, althou I've checked my configuration against ALL the online tutorials, and it seems fine to me. I've also checked /var/log/mail.log and there's no word "SASL" in it.

Please take a look at my complete description of the problem here: http://serverfault.com/questions/532817 ... ot-present

Do you have any ideas?

Thank you!

I answered your serverfault question with what I believe to be the correct answer, assuming the rest of the configuration is also correct.

Thanks, I've also replied.

I've set smtpd_tls_auth_only = no , but still no traces of SASL.

That log is meaningless, the mail is coming from gmail so it won't try to authenticate.

If you didn't redact the IP/domain from your config I could test, but you did (what's the point of asking for help and hiding info?) What did it say when you used openssl? No trace of AUTH whatsoever?

EDIT: I saw your reply about plaintext auth on serverfault. Check my comments.
