DSBL vs Spamassassin???

Postby KKJensen » Fri Sep 08, 2006 10:15 am

Hi there,

(Before it was stolen in a breakin) we had a small linux machine running our mail server which used a service from dsbl.org that black lists senders for spam. This was used to filter mail upon arrival and toss anything that had been blacklsited.

Years later we're looking at doing our own email server again (scalix of course!)because our current provider is doing a terrible job at protecting us from spam and now I'm curious about what there is out there and how it all works. The boss is familiar with dsbl but scalix seems to have a connection to spamassassin.

Any feedback or comments or testimonials would be greatly appreciated!

KKJensen,

Please refer to the following link:

http://www.ordb.org/faq/#usage_sendmail

quote
Sendmail
sendmail.mc: FEATURE(`dnsbl', `relays.ordb.org', `"550 Email rejected due to sending server misconfiguration - see http://www.ordb.org/faq/\#why_rejected"')dnl

This works for version 8.10 and later (which is recommended, see also Which version of sendmail should I run?)

For version 8.9 the syntax is FEATURE(`rbl', `relays.ordb.org')dnl (see also under http://www.sendmail.org/~ca/email/chk-89f.html#MAIL)

For version 8.8 (or less?) find a place in your sendmail.cf to hack in code like

R$* $: $(dequote "" $&{client_addr} $) R$-.$-.$-.$- $: $[ $4.$3.$2.$1.relays.ordb.org $] R$-.$-.$-.$-.relays.ordb.org. $#error $@ 5.7.1 $: 550 no access from [$4.$3.$2.$1], see http://ordb.org/

(You may refer to http://www.sendmail.org/~ca/email/check.html#check_mail for additional information.)


Hope that helps!
