[You didn't mention the Mailman version you run... I guess it must be a 
V2 of some sort due to the qfiles mentions - I'm using 2.0.3 and so a 
couple of comments below might be wrong if you are running anything 
much earlier]

I at first assumed you are injecting mail with SMTP and that the SMTP 
handler was broken... however a look at smtplib.py shows that it does 
double leading periods on lines, and so that is as it should...

In which case you must be using the Sendmail.py interface.  I've 
commented on this on the list before... I personally wouldn't trust any 
mail I wanted to get out to this handler.

The practice of terminating a message with a single period is part of 
SMTP, but some unix dumb MUAs used it too... and some sendmail's hence 
also do it :-(
I'm very lucky in having no sendmail instances and no sendmail 
documentation here, so can't check the option you need to prevent this 
behaviour - however exim's sendmail compatibility mode uses -oi to do 
this.

You appear to have 2 options in this:-
  1. Change the definition of SENDMAIL_CMD in your site defaults and
     add a -oi flag (although I would check this first).

  2. Move to SMTP injection.... it has so many advantages
