mail blockers

[Sergey Matveychuk]

Just warning: I can't answer on your bug reports if you block my mail 
servers:

erik at erikserver.com
    SMTP error from remote mail server after MAIL FROM:<sem at FreeBSD.org>:
    host mail.erikserver.com [68.146.11.102]: 553 5.3.0 REJECT See 
http://erikserver.com/spam.html

and give me no chance to unblock.
Yes, I know, too many spam from *.ru. But block all .ru is fun.
