The major difference between traditional Frontfree Mail System and this is:
Currently the settings are:
Strict RFC821 Envelop.
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.
I have turned on several anti-spam settings on beastie.frontfree.net to ease my life. They stand for “most evident spam characters” and hence should not go to the content filtering subsystem and should be directly dropped.
It seems that sina’s bad-brainly designed anti-spam system is going to do more foolishnesses. By applying their RFC-violence, they did not blocked spam and in addition, make normal mail slow and even not deliverable.
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.
It’s believed that blog is going to be a victim of business spams, after mail spams :(
