Hello all, this is my first time posting on this list so be kind :)
I have a postfix/amavisd/spamassassin box acting as a gateway to my
Exchange server. Everything seems to be working ok except I am a bit
confused about how banned attachment names are being handled (.exe
in particular).
I use postfix's mime_header_checks to reject all mail with bad file
attachments
and this is working fine except for .exe files. It seems as if amavis
is picking
these up and notifying me for some, but not all exe's. Below is an
excerpt of an
amavis report I receive.
My question is this, in what order are the postfix/amavis rules
processed?
When I send an exe file to myself from the outside I get a reject from
*postfix*
not amavis, however, I still receive message similar to below on a daily
basis.
Any ideas? Thanks in advance.
Jack
