Mailscanner blocks attachment with extension .BS4PRJ

Post by p88 » 12 Feb 2018 08:52

Hi,

my mailscanner configuration blocks emails with correct file attachments with the extension "filename.BS4PRJ".

The rule triggered is:
MailScanner: Dangerous attachment according to Microsoft Q883260 (filename.PST) .

There is no attachment with an extension ".pst" in these emails.

I added the "allow \.BS4PRJ$ - -" to filename.rules.conf but that doesnt help.
I removed the "deny \.pst$ - - " from filename.rules.conf but event that doesnt help.

What is wrong here?

Is BS4PRJ an archive?
Version 3.0.2.6 released! Update now to keep your eFa secure!

This is not an archive. It is a database of an cad application.
I changed the archive rules too.
I can reproduce this behavior/problem with a simple txt file renamed to that extension and send to efa as attachment.

I cannot confirm this. An attachment with the extension BS4PRJ passes right through my installation.

Can you run the following commands and post the results here?

Code: Select all

cd /etc/Mailscanner/
grep -r -i "Q883260" .

Ok,

i rechecked the syntax of the pst deny and there was a tipo in there.
It is working now.

Thank you!
