Default Sendmail/Spamassasin/Spam

Hey,

I'm hosted on Verio VPS Red Hat Enterprise 3.

Haven't spent a lot of time with Sendmail, but i'm getting
pissed with all the spam, and probably need a basic understanding
of the mail services.

Using:
Sendmail 8.14.4
SpamAssassin

Can I setup (similar to IPTABLES), reject all mail
except from specific domains using the access db?

I've seen some samples, but not specifically what I want to do....
or is this not a good idea.

As always, thanks.

RHEL3? Geeze! That went end-of-life a LONG time ago!

What you're asking to do is a "whitelist" (a list of servers or domains
allowed to send mail to you). This can be become difficult to support--
depending on how big your whitelist will be. Alternately, you can
subscribe to a "blacklist" such as spamhaus to block known spammers.
In other words, as long as the sender isn't on spamhaus' list, they can
send you mail.

I'd suggest googling whitelist and blacklist and reading those articles.
There's also good articles on using things like Spamassasin and other
filters (lookup "sendmail-milters").

Also note that sendmail can be a right bitch to manage. You might be
better off with postfix. Much easier to manage, if not as flexible as

sendmail. It's really easy to shoot oneself in the foot with sendmail.

Check out some of the RBL's you can install using the vinstall command.
I believe most VPS' came preinstalled with at least one RBL, however you
can install a number of additional lists. You could also try adjusting
SpamAssassin sensitivity to handle some of the spam. Not sure how the
newer cpanel VPS servers handle the spam issue.
