Problem with MS blocking legit attachments

[Brendan Chard]

Possibly in the filename.rules.conf file.  The last 2 lines:

# Deny all other double file extensions. This catches any hidden filenames.

deny    \.[a-z][a-z0-9]{2,3}\s*\.[a-z0-9]{3}$   Found possible filename
hiding Attempt to hide real filename extension

Subject: Problem with MS blocking legit attachments

Hello everyone.

This morning, MS started to block legitimate emails attached with .doc
files. So far, I have had 3 blocked today.
They are all .doc files (all resumes actually) and im trying to figure out
why they are being blocked.

Looking through the logs as well as MailWatch, I see this in the headers
field:


MailScanner: Attempt to hide real filename extension (Resume.kari.doc)


I can't release it from quarantine, as it gets put right back into the
quarantine directory.

I've looked through my .conf file, but haven't been able to figure out what
this is happening.

Anyone have any ideas?

System:

FreeBSD 4.9
MS 4.29.7
Sendmail 8.12.11

I appreciate it

Jason
