That's sad. :(
A lot of mailboxes on my server receive 20 - 50 may be more emails from empty sender per day. 99% of that emails are spam. So people have more then 50% of spam emails on their mailboxes. I know that XMail, EXIM, Postfix, Sendmail, ZMailer can stop that emails (from empty sender). And I think this is good idea. I used this feature all the time. But now I have a lot of spam. I think it's possible to stop emails from empty senders in courier also, but I just didn't found how to do it. Am I wrong?

Hello everybody,

Does somebody know how can I configure courier-mta to reject empty senders like:
MAIL FROM: <>


I hope that there isn't such a config option as you are required by the
RFCs to accept such mail or your users won't receive bounce messages.
If you *do* manage to reject those mails you will get on several RBLs
very soon - and right so.

Cheers,
Juri
