Can you understand where messages are created?
If they are created outside -email system, they should not be accepted.
If they are generated inside the system, or coming from a trusted system
(for which you don't apply chkuser), they are always accepted.
Check carefully.

Hello,
I found a problem on chkuser. Maybe there is a solution, that I don't know.
If I sent e-mail from e.g. Gmail to [EMAIL PROTECTED] which domain.com hosted
in my qmail, chkuser blocks it and says
PERM_FAILURE: SMTP Error (state 13): 550 5.1.1 sorry, no mailbox here by
that name (chkuser)
Hi Zeki,
this problem is already known.
I have to add this check to chkuser since one year, but I had no time
until now.
I have a bunch of fixes/features to add, I will try to find spare time
and fix them.
Thanks,

Does chkuser support checking for users in /etc/passwd? I installed Toaster
v 0.9.2. chkuser works on virtual domains fine, however, local addresses
are accepted by chkuser regardless of whether they're valid or not.
Is there a way to have CHKUSER log the connections

The log for SMTP is the /var/log/qmail/smtpd/
