Summary: Incorrect escaping of dots in SMTP sessions

Initial Comment:
SMTP requires the client to "escape" any line that begins with a period (.) by 
adding an additional one in front. Receiving MTAs strip the first period from 
every line, and add them back if delivering via SMTP.

Dspam only escapes the dots in certain situations, meaning that other messages 
can be silently corrupted. This can be catastrophic in certain cases (e.g. PDF 
files), but is generally pretty bad form in all cases.

The attached patch seems to correct the issue, by moving the escaping to the 
SMTP sender part of the code. It was not written by me, but supplied to the 
devel mailing list in February.
