MailScanner denies the files with these extensions
- These are known to be dangerous in almost all cases.
[.reg], [.chm], [.cnf], [.hta], [.ins], [.jse], [.lnk],
[.ma[dfgmqrstvw]], [.pif],
[.scf], [.sct], [.shb],
[.shs], [.vbe], [.vbs], [.wsc], [.wsf], [wsh], [.xnk]
- These 2 added by popular demand - Very often used by viruses
[.com], [.exe]
- These are very dangerous and have been used to hide viruses
[.scr], [.bat], [.cmd], [.cpl], [.mhtml]
- Deny filenames ending with CLASSID's
- Deny filenames with lots of contiguous white space in them.
Example: [A Presentation for Ecoloy and Evolution.ppt]
- Deny all other double file extensions. This catches any hidden filenames.
Example: [Presetation.doc.pdf]
If you feel some of the file names should not be detected
as bad attachement that contains dangerous[virus] codes,
also, if you feel some other files should be detected as
dangerous attachments, please let me know.
I'll be happy to re-configure MailScanner to allow or deny
those files to get through or stoped by our email server.
