Postfix not receiving mail or being connected to by email servers
I have setup a postfix server with dovecot, and i can connect and send emails fine. The only problem i have is when i try and receive emails; Sometimes google (test account) connects, but when it does, i get an SSL-ACCEPT error.

myhostname = mail.[redacted].us
