help with sendmail 8.9.3 on 3.1
Theodore Hope
sendmail (8.8.5), I decided to install sendmail 8.9.3 from source.
I'm having trouble getting the various anti-spam restrictions
working in harmony. The situation is:
+ Many virtual domains, using /etc/virtusertable (hash) and
/etc/sendmail.cT.
+ Want to accept mail if the From _or_ the destination is one
of our local domains, reject otherwise.
+ We don't provide dial-up service to our users, so we can't
block based on where they're coming in from.
Right now it either rejects all mail not coming from my domains
(not good), or accepts anything (except from invalid From domains).
I've based my main ".mc" file on the bsdi.mc that's distributed
with 4.0 (for sendmail 8.9.0, I believe), and have the following enabled:
FEATURE(relay_entire_domain)
FEATURE(relay_based_on_MX)
FEATURE(access_db)
FEATURE(blacklist_recipients)
#
FEATURE(mailertable)
FEATURE(virtusertable)
define(`VIRTUSER_CLASS', `T')
define(`VIRTUSER_ERR_NOUSER', 1)
I set up /etc/relay-domains (and it's corresponding hash .db file)
with a "xxx.xxx OK" for each xxx.xxx domain we have. (They're also
in /etc/sendmail.cT .)
Right now we're still being used as an occasional spam trampoline,
and have most likely gotten on the RBL and other black lists :-(
I've RTFM & RTFWWW and still can't get it all to work together.
Thanks for any hints.
-T.
