Hi,
I am still trying to figure out this issue as well.
In reference to the error log.
Nov 11 02:13:50 vps postfix/smtpd[11177]: connect from unknown[122.154.46.172]
Nov 11 02:13:53 vps postfix/smtpd[11177]: warning: unknown[122.154.46.172]: SASL LOGIN authentication failed: UGFzc3dvcmQ6
Nov 11 02:13:53 vps postfix/smtpd[11177]: disconnect from unknown[122.154.46.172]
Nov 10 19:24:06 vps postfix/smtpd[12743]: NOQUEUE: reject: RCPT from localhost.localdomain[127.0.0.1]: 454 4.7.1 <email@gmail.com>: Relay access denied; from=<apache@localhost.localdomain> to=<email@gmail.com> proto=ESMTP helo=<localhost.localdomain>
Not sure if this helps spread any light on the issue.
