Well, when someone send a message with a non-allowed attachment, MD try
to send a return message and if the from: field is <> /var/log/messages
start to record "please try again...". If I restart MD & Sendmail all is
fine.
The attachment contain my mimedefang-filter.
How can I resolve this problem?
