I had setup a qmail box for a customer with many patches:

spf from spf.pobox.com
discard feature I had written myself
This install uses q-s for all external (non-relayclient) incoming connections.
It has also setup helocheck and mfdnscheck (see spamcontrol).
This box has been working perfect for 10 days and esterday night, around 9:50pm, this box suddenly became an open relay. All new connections was having set RELAYCLIENT. In tcp.smtp, I don't have RELAYCLIENT set for last allow rule, only checks above and QMAILQUEUE to call q-s.
With q-s I have only clamav-0.81 to get rid of (some) virus.
I have softlimit set in qmail-smtpd service to 30000000.
Can anyone provide a reasonable explanation for this?? Might be related with ClamAV or Q-S issue??
(I am sure it is related with one of them...)
The REALYCLIENT check (and decision, rcpthost ->
'addrallowed') is done by qmail-smtpd, so before qmail-queue (or q-s)
is invoked.
Maybe one of the patch that modifies
qmail-smtpd.c has broken this check... You can also check your
rcpthost file.
