Hi all!

We have a strange problem:
A forward rule is working for nearly all incoming mails.
But there are mails, which can't be forwarded (it is not important if
its a flat forward or not). These mails are typically mails to inform,
that a mail could not be delivered, for example they are from

From: Mail Delivery System <MAILER-DAEMON@****>

I couldn't find a pattern until now.
In the POA - LOG file I can see, that the forward rule is executed, but
the forwarded Mail is not transferred to MTA/GWIA.

Has anyone seen something like this?

Thanks in advance
