The more services you subscribe to, also, the more
legitimate mail you reject. You will reject tons
of legitimate mail with ORBS, since ORBS lists
multi-level relays. Thus, every ISP which does not
implement the ORBS-approved anti-spam policy (i.e.
either subscribe to ORBS, or block all port 25
traffic to customers) can have their customer relays
listed in ORBS.
Using ORBS as a blacklist is fine for your personal
mail, or for an "internal mail only" server (e.g. in
a fascist workplace), but is pretty irresponsible
otherwise, IMNSHO.
To be fair, ORBS is a great tool for nominating spam
relays to the RSS ;-)
> PS: how to do that using rblsmtpd ?
With stock rblsmtpd, you chain the rblsmtpds:
rblsmtpd -rrbl.maps.vix.com rblsmtpd -rrelays.mail-abuse.org \
rblsmtpd -rdul.maps.vix.com rblsmtpd -rrelays.orbs.org \
rblsmtpd -rin-addr.arpa qmail-smtpd
However, with the multi-rbl patch (mentioned a few days ago on
this list), you can specify multiple blacklists as multiple -r
arguments, as in:
rblsmtpd -rrbl.maps.vix.com -rrelays.mail-abuse.org \
-rdul.maps.vix.com qmail-smtpd
