Hi,
I've been trying to get SSL/TLS email working for 2 days now with now such luck, my latest mail.log error is:
Feb 9 12:56:09 One postfix/smtpd[6617]: NOQUEUE: reject: CONNECT from unknown[x.x.x.x]: 554 5.7.1 <unknown[x.x.x.x]>: Client host rejected: Access denied; proto=SMTP
and my config is below. Can anyone spot anything that is wrong? Any help would be great appreciated.
