This is driving me crazy!!! Weeks have gone by, been working fine using Starttls... and now, after a server reboot, due from an update, it now does it again..
I can only send email now if I do not use authentication - but even though I try:
root@server:~# telnet localhost 25
Connected to localhost.localdomain.
Escape character is '^]'.
220 server.christiancoalition.co.za ESMTP Postfix (Ubuntu)
250-AUTH PLAIN LOGIN
221 2.0.0 Bye
Connection closed by foreign host.
IT expects it.... But NO matter what I try, it does not accept connection with STARTTLS.... WHY WHY WHY???
