are there good options for anti virus. for linux mail servers and file serves.
Hi
We use ClamAV with MailScanner on our mail servers. Does a pretty damn good job of it. I don't think we've got a report of any virus slipping through except for one.. I think it was called bagle which required really dumb users to screw themselves. It sent a zip file with a password and in the mail it provided instructions and the password to open the zip file and execute the virus.
But in about a couple weeks the MailScanner team figured out a way to deal with Password protected zip files or something which is not bad for something that we did not pay money for. :-)
Also there are rules that you can customize which do not permit bad extensions through like .exe .pif and .scr etc. so if it's a new virus and ClamAV can't detect it MailScanner quarantines the attachment and sends a notification to both sender and receiver ... The system administrator can then later retrieve it for the receiver.
I've never used one on Samba (File Server).
Hope this helps.
