Postfix

Today I have finally get postfix 2.1.1 running on beastie.frontfree.net (2.1.0 lived there for four hours before it was replaced with 2.1.1 after it replaced 2.0.20 :-) )

Wietse Venema has released postfix 2.1-RELEASE, after a prolonged test and release cycle. postfix 2.1 has several major improvements over the postfix 2.0 series, the documentation is completely rewritten, and the anti-spam features is extensively improved.

Wietse Venema has released postfix 2.1-RC5 yesterday, and this is expected to be the final Release Candidate of postfix 2.1-RELEASE.

It seems that postfix 2.1-RELEASE will include an amazing feature called “policy server”, which can be used to implement greylisting, a brand new and effective technique to fight against spammers.

Sorry for my ignorance, but it seems that NetBSD has imported postfix to their source tree for at least a year!

With more and more aaazzz’s received on beastie.frontfree.net, it makes me to seriously consider the possiblity to set up a set of early filter on postfix.

There are two common way to process unaccepted letters: One is bounce, a.k.a. give the sender a message saying “Your letter is bounced.” Another is discard, in other words, drop the letter silently.

太多了，太多了……

+1 -1: #strict_7bit_headers = yes

Gibe is still the first place, and MyDoom(here, it was called Worm.SCO.A) drastically dropped down.

beastie# bzcat maillog.0.bz2 | grep INFECT | awk ‘{print $8;}’ | sort | uniq -c | sort -rn
181 (Worm.Gibe.F),
86 (Worm.SCO.A),
2 (Worm.Dumaru.Y),
1 (Worm.Sobig.F),
