How to use sSMTP with CSF?

[curiosus]

I am using a very minimal Debian Squeeze server. I don't have a mail server installed.

I've already installed sSMTP (wiki . debian . org/sSMTP) and was able to properly configure Gmail as the SMTP server.

My question is how can I use this so that CSF will use sSMTP when sending email alerts?

After weeks of agonizing research, I just decided to enable all outgoing TCP6 ports.
