Re: howto stop wrong replay mails ?
There are viruses/trojans that can send mail in behalf of other people. There is no way to prevent that.
Masquerade the "from:" of a message is very easy.

our mail address is: webmaster@domain.net
I think someone from outside with the mail address: 62.138.253.55 try to send mails using our mail address to: MailIn_Box@aol.com, but this mail address doesn't exist by AOL and we get:
Returned mail: User unknown
mails in our postmaster, ca. 1000 a day
that is very annoying

You can also filter based on the subject by using procmail. See:

Report the violation and the user will lose his account in a few minutes.
It could be someone in germany figured out how to relay through an aol mail server and once again, aol needs to know about it so they screw the security tighter on their system.

If this is coming from a single source, simply add an access record:
mail1.highwayone.de REJECT 550 no more spam.
You may need to do an m4 sendmail macro build, but that entire domain will never send mail again with my recommended change.
Does it all come through aol?
The fastest fix in that event is the aol postmaster.
