no subject messages

[Angelo Caruso <angelocr @ tin . it>]

Some of my users don't write a subject for their messages to the list. What
I find a little bit annoying is that, in the case, also the subject prefix
I wrote in the config file doesn't show.

While I try to convince the folks that a subject is really useful, is there
a solution to this ?

Thanks a lot,
Angelo Caruso.
