Description igmar 1999-09-13 05:21:14 EDT

I just noticed that sendmail allows empty From lines :

Mail From:<>
250 <>... Sender OK

This should't happen, as it is supposed to check the domain
from the sender.

Just looked at the RFC's, and it is supposed to work this way. So
please kill this one :-))

Now to find the use of this behaviour...
