Re: Content-type restrictions

[Mats Bengtsson]

At least you have managed to slow down the mailing list
server (well, probably it's the number of virus emails
that is the largest culprit), I didn't receive this email
until friday afternoon and it was apparently sent out on
wednesday.

Do the rejected emails bounce back to the sender? In that case,
many people on the list will still suffer from a large number of
virus emails, since the fake From: address often is taken from
the same list of email addresses where the virus found the mailing
list.
Still, for serious emailers who want to reach the mailing list it's
important to get some response about why the email was rejected and
how they can get around it (this should also be documented at
http://lilypond.org/web/about/ or
http://mail.gnu.org/mailman/listinfo/lilypond-user )
