Hey, I'm hosted on Verio VPS Red Hat Enterprise 3.
RHEL3? Geeze! That went end-of-life a LONG time ago!
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.
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. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - "How does that damned three seashell thing work?" - - - Sylvester Stallone, "Demolition Man" - ---------------------------------------------------------------------- _______________________________________________ Redhat-install-list mailing list Redhat-install-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/redhat-install-list To Unsubscribe Go To ABOVE URL or send a message to: redhat-install-list-request@xxxxxxxxxx Subject: unsubscribe
