RBL?

[bmahaffey]

is there an RBL setting i can configure on the mailservers to access
sbl-xbl.spamhaus.org ? thanks.

[bmahaffey]

Does anyone know how to do this?

QMR Admin: Hey on your next release of Qmailrocks could you possibly create a section on how to configure a RBL setting? please.

Thanks

I agree - RBL, Razor and Pyzor support for SpamAssassin is a fairly simple but hugely useful additional step to this guide.

I am slowly working my way through these but it's amazing how foggy the dozens of guides are on the 'net in this area, considering the spam issue worldwide!!

Yeah I get a ton of spam. The spam filter works great for the first couple of months (im guessing the spammers are able to get around old technology) but after that it gets ugly, im not talking 4 to 6 emails a day but over 40 sometimes.

There is support directly within qmail-smtpd that works with rbl.

Check
http://cr.yp.to/ucspi-tcp/rblsmtpd.html

All you need to do is modify your qmail-smtpd run script.

Change the exec part to something like:

exec /usr/local/bin/softlimit -m 30000000 \
/usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
/usr/local/bin/rblsmtpd -b -r list.dsbl.org \
-r cbl.abuseat.org \
-r combined.njabl.org \
-r relays.ordb.org \


You can change the sources used by adding or removing the lines "-r whatever_rbl_source"

This will deny messages at the smtp level. Works pretty well actually...

What happens if one of those sites go down? Is qmail smart enough to time out or will it jam and make all mail stop?

[vxaxv]

Im not totally sure (i dont even use rbl myself), but this may provide more information.
