Re: SMTP servers
said by KoolMoe  :Does 'SSL-encrypted' SMTP authentication require an SSL certificate? If so, those can be pretty expensive. I use 'TLS if available' and my home-run SMTP server without any problem... KM If all you're looking to do is encrypt your session, you can use self-signed certificates. Those are free. All you gotta do is generate one. There are dozens of tutorials on how to do so.
If, however, you want MTA-to-MTA traffic to be verifiable, then each MTA has to either have a verified copy of every certificate presented or the sending and receiving MTAs need to have their certificates from a common authority that both recognize as being valid. The "common authority" certificates are the one that are expensive.
You don't, however, need verification to perform encryption. So, use self-signed certificates and save yourself a non-trivial chunk of change.
