Sorry about a typo in the mail below. I have put
the entry

Subject: How to prevent smtp from
accepting blank From: field
I am having a problem with my site where someone
is trying to spam the site with
some message titled "Snowhite and Seven Dwarfs".
The From: field is being shown as From: [EMAIL PROTECTED]
mail from: [EMAIL PROTECTED] is not being accepted
by qmail-smtp. However inspite of this mails keep on coming from this site. It
seems that the the smtp dialogue is being done in he following manner (i.e. a
blank mail from: is being given)
telnet 0 smtp
Trying 0.0.0.0...
Connected
to 0.
Escape character is '^]'.
220 ESMTP
mail from:
250
ok
rcpt to:<[EMAIL PROTECTED]>
250
ok
data
354 go ahead
From:Hahaha <[EMAIL PROTECTED]>
Subject:
Snowite and the seven dwarfs
.
250 ok 984632317 qp 4283
Any suggestions on preventing blank mail from:
being given during smtp dialogue?
Regards Manny
