The company I work at has a regular qmail install (not a toaster) with
courier-imap, squirrelmail, qmail (1.05) vpopmail, etc. It's quite
similar to a toaster setup but it doesn't seem to have the bells and
whistles that make qmail an efficient and effective MTA.
The problem I'm having with this qmail install is that it is accepting
email from null senders and it's filling up the queue with emails
because
it can't bounce the emails as there is no from address.
qmailctl queue shows similar output to this:

There is a rcpthosts file listing only the mailserver's domain and
such so
it isn't being used as an open relay. I noticed that my toaster had a
badmailfrom file with the following contained within it:
.*\ @.*
[EMAIL PROTECTED]
.*%.*
So I added this file in /var/qmail/control on the qmail instance and
hoped
this would take care of the problem but it isn't. Is there a certain
patch that I can install that will fix this problem or a certain file I
can add that will fix the problem I'm having?
Any advice or references to solutions would be great.
Cheers,
Jon
QMT uses CHKUSER, which will check to make sure (at SMTP time) that a
user exists before accepting the message. It rejects at SMTP time if
the recipient doesn't exist, thereby eliminating the problem of a
queue full of messages to non-existent recipients.

There is also a patch called validrcptto which does this same type of
thing, but is a bit more flexible IMO.
http://qmail.jms1.net/patches/validrcptto.cdb.shtml
Implementing either one of these solutions will help you greatly.
