it's more than a week now that I'm "playing around" with qmail and all the other stuff. Everything is working fine on my rh 7.2 box:
but the probably easiest thing to setup, but most important thing is not working: smtp authentication
I start the smtp server with /var/qmail/supervise/qmail-smtd/run which looks likes this:
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g qmaild`
exec /usr/local/bin/softlimit -m 2000000 /usr/local/bin/tcpserver -v -R -H -l 0 -x /home/vpopmail/etc/tcp.smtp.cdb -c "$MAXSMTPD"
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1
When I start this script port 25 of my server opens and it relays. I did test it by using another connection to be sure my IP is not already authentificated.
Further I've noticed that vpopmail writes my ip address inside /home/vpopmail/etc. This file does only contain my ip address as soon as I check my mailbox.
Thanks a lot for your help!
P.S. I'm not sure where the error could be, therefore I'll be happy to post every info you need. I do not want to overflow you with potential unimportant data right now
