Title: Inserts an extra dot at the begining of a line if it starts with a dot

This patch will add an extra dot at the begining of the lines that starts with a dot when they are sended with the client. If you don't do that, the SMTP servers will remove this dots.

I detected this problem because DKIM signed messages will not pass the checks.

See RFC 2821 Section 4.5.2
