Looks like the email server's SSL certificate has expired.

Looks like the email server's SSL certificate has expired.

But ssllabs gives me an "A" rating for the mail server.

If you look at other elements of that log, it's server.foreveryours.us that the message is logged against. Perhaps your email isn't set up properly?

[pixelpadre]

A rating with cert for server.foreveryours.us also.

Im not having a problem with smtp auth using thunderbird.

Looks like the email server's SSL certificate has expired.

(yum update ca-certificates -y) Fixed the expiration issue but still no joy.

Not sure why there is a mismatch in the chain. But setting the smtpauth to server.foreveryours.us eliminated the mismatch and mail was sent successfully.

postfix/main.cf question:

# network settings
inet_interfaces = all
mydomain = yourdomain.com <-----------------------does this matter? This is the default postfix settings
myhostname = server.companiondriver.com
mynetworks = $config_directory/mynetworks
mydestination = $myhostname = server.companiondriver.com
relay_domains = proxy:mysql:/etc/postfix/mysql-relay_domains_maps.cf
