how to setup TLS for smtp

[Illidan]

Hello,

How do you mean that gmail requires TLS or SSL? Do you send your mails about a gmail relayhost?

TLS is a complicated thing, if you haven't a paid certificate you have to create them and sign them self.

Befor you start explain first if you only want to add the certificates from gmail to your server so that your server accept them or that you want to create own certificates to send mails via TLS/SSL.

Here is guide for creating and using self signed SSL certificates.
