On local host I can connect to the SMTP server using basic authentication on port 25 but I cannot connect using tls or ssl. (I am trying to connect from code).
I have tried ports 465 and 587. (I cannot telnet to 587 but I can to 465).
I just get "Connection refused" from my client library.
I don't really know what I should be looking for. There is no SSL certificate for mail on the domain - but I don't think that matters. The server mail certificate is the default. The server web certificate is one for a domain - but that is for web access, not mail.
I don't really know what I should be looking at. AI is suggesting editing a posffix config file, but I would rather avoid that.
