After being away from system administration duties for a long time, I
have returned. My current motivation is to bring down the SPAM in my
private server.
These are the 3 lines of defense:
(1) Added the lines shown below to the file /etc/mail/sendmail.cf.
(2) *SpamAssassin*. Implemented this week. Currently running "sa-learn
--spam" almost on a message by message basis. The results are very
promising. I am considering migrating from procmail-based to
MTA/sendmail-based. Somehow it seems that taking procmail out of the
equation would result on a slightly more reliable system? Pros? Cons?
(3) My e-mail reader, Thunderbird. Every time I opened it had to spend a
lot of time marking junk mail. That's when I decided to add SpamAssassin.
Due to the deluge of SPAM, my impression was that the spamhaus+spamcop
combo was not working very well. However, upon closer inspection I
noticed that about 7,000 messages are being rejected each week. BTW: I
am guessing that spamhaus by itself is sufficient, since spamcop only
rejected 3 messages that were missed by spamhaus.
Any comments, suggestions are most welcome.
TIA,
