Now that I tested, (with ~/.signature), composing new mail starts with

--8<---8<---8<---8<---8<---8<---8<---8<---8<-
From: Tomi Ollila <tomi.ollila@iki.fi>
To:
Subject: 
Fcc: /home/too/mail/mails/sent
--text follows this line--

--
signature
--8<---8<---8<---8<---8<---8<---8<---8<---8<-

Notice the empty line between '--text follows this line--' and '--'

In your example, the signature block is -- for some reason --
inserted without the empty line.
