Need to allow blackberry EPT.DAT files

Some offices of the college are being affected by some blocked data
files. They are .dat files and we do not want to unblock .dat files.
I am told in this case the data files are part of syncing blackberry
applications to desktop applications.
I considered allowing EPT.DAT, but that seems like too much of an
opportunity for the wrong persons.

Here are some of the facts:

Report: MailScanner: No programs allowed (ETP.DAT)

Would it take a custom modification to 'allow EPT.DAT files only from
*' or could a file rule accomplish it?

The filename.rules.conf seems to not be able to deal with the domain

Looking at it seems there could be a
/etc/MailScanner/spam.bydomain/whitelist/blackberry file if everything
from and from prod.on.blackberry was wanted to be
allowed. As I have no idea what mail could come from
those it does not seem wise to just open for everything from them. [I
have not found a way to ask blackberry/rim any questions.]
