auto-reply infinite loop - autoreply yourself

[simple]

Hi there,

I could find no good solution for one problem: I have auto-reply activated for 2 mail accounts, and write a message from one to the other, they autoreply themselves to death. 100 messages in an hour and more, each telling the other, that this is an automated message, and the mailowner is not available right now. That loop should be stopped after X mails, or not even happen when "autoreply" is in the subject.

Someone a hint?

greets
Markus
