For some weird reason procmail is filtering the test messages with .scr files attached that i send myself using any external email adress.
Its send them to /dev/null like it should.

But i'm still getting tons of messages with those viri attached from others.
I can see in the procmaillog that they are processed, but for some reason he does not recognise them as infected.

Is the some trick involved with the scr filesnames that mislead procmail?
Or can someone think of any other reason?

Any help is appriciated.
Thanks in advance!
