Newer Postfix versions log this.

Older Postfix versions would send mail to postmaster if you had
turned on protocol trouble reporting, and I was getting annoyed by
several of these in a day. Protocol error reporting is for solving
compatibility problems, not for telling you that there are idiots
on the network.

Postfix now drops the connection with an "I can break rules, too"
message.
