move the system (Postfix) to a different version of Linux (Debian).
Everything is working fine and all users are 100% happy with the new

I had a user ask me if the Postfix email server can auto respond w/
"Out of Office" reply rather than do this on his client in case his

Thanks - so basically this is not specifically something my Postfix

It appears that my postfix server is using invalid TLS certs from
/etc/postfix/main.cf. When I set up my client to use TLS, I get an
