Hi.
I want to run qmail with smtp auth, so i patched qmail with yaqsap (yet
another qmail smtp auth patch).
i run qmail-smtp with
#!/bin/sh
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
exec /usr/local/bin/softlimit -m 2000000 \
/usr/local/bin/tcpserver -v -p -R -H -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd \
mail.mydomain.com /home/vpopmail/bin/vchkpw /bin/true 2>&1
so as you can see, i use the three arguments
"hostname" "checkprogram" "true"
as yaqsap also patches the qmail-smtpd man page i'll post an extract of it
too:
# man qmail-smtpd
NAME
qmail-smtpd - receive mail via SMTP
SYNOPSIS
qmail-smtpd [ hostname checkprogram subprogram ]
DESCRIPTION
.....
qmail-smtpd can accept LOGIN, PLAIN, and CRAM-MD5 AUTH
types. It invokes checkprogram, which reads on file
descriptor 3 the username, a 0 byte, the password or chal
lenge derived from hostname, another 0 byte, a CRAM-MD5
response (if applicable to the AUTH type), and a final 0
byte. checkprogram invokes subprogram upon successful
authentication, which should in turn return 0 to qmail-
smtpd, effectively setting the environment variables
RELAYCLIENT and TCPREMOTEINFO (any supplied value replaced
with the authenticated username). qmail-smtpd will reject
the authentication attempt if it receives a nonzero return
value from checkprogram or subprogram.

well.
when i try to use smtp auth from a client (in this case i tried outlook
express with auth login)
qmail tells me:
Out of memory (Needed 8164 bytes)
454 oops, problem with child and I can't auth (#4.3.0)
after the username and password are send.
someone in the qmail list has suggested to leave out the hostname argument,
which indeed solves the problem, but it doesnt check for valid passwords
then. (i guess it then uses /bin/true for password checking)
do you have an idea of what that "out of memory" message wants me to do ?
/home/vpopmail/bin/vchkpw exists, is world executable, i even tried to
setuid it, but nothing happens. when i run qmail-smtp as root, the same "out
of memory" occurs, too.
i use /home/vpopmail/bin/vchkpw as checkprogram for qmail-popup
/usr/local/bin/tcpserver -l mail.mydomain.com -v -p -R -H 0 pop3 \
/var/qmail/bin/qmail-popup mail.mydomain.com /home/vpopmail/bin/vchkpw \
/var/qmail/bin/qmail-pop3d Maildir
And it works fine.
Best Regards,
Justin
