Mailscanner blocks attachment with extension .BS4PRJ

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?

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!
