whitelist a file from the content scanner

[Simon Annetts]

Hi,
I need to be able to stop mailscanner from virus checking and filetype 
detecting a particular filename so that our support team can send 
updates via email. The file will always be called (for example only:) 
update.zip and may contain .exe and other type files that are normally 
banned.

At the moment mailscanner always rejects the file and quarantines it 
because it is in the banned filetypes list. If I exempt .zip files or 
specifically update.zip then mailscanner proceeds to unpack the file and 
quarantine any files inside which also are banned. This is all good 
stuff as far as mailscanner doing its job, but I want this file to pass 
through mailscanner completely untouched/unchecked. I want to exempt 
this file name from all checks,  - spam virus content and filetype.


Is this possible???
Best Regards
Simon
