[SoCoSA/discuss] exim TLS cert problem

[Sean]

Kevan, thank you that openssl command was very helpful. It shows the
www cert being passed for my secure email ports (pop, imap). Now I
just have to figure out why it's not using the defined values to send
the mail certs.

Nicholas thank you for that link. I read that document yesterday and I
did not find anything useful. I'll probably read it again if I can
find the time.
