[gentoo-user] Outgoing emails don't seem to be encrypted with TLS through

[napalm]

postfix
Reply-To: 

All of my incoming emails are coming through postfix, eg that last email
left this beauty in the log:
        postfix/smtpd[13698]: Anonymous TLS connection established from 
pigeon.gentoo.org[208.92.234.80]: TLSv1 with cipher AECDH-AES256-SHA (256/256 
bits)

I'm a bit lost as to how to get my mails to *send* encrypted though.

Is there a setting in main.cf that I'm missing?

Thank you!
