Yes, I do block all .exe files, but my filter behaves differently if it detects a virus. If there is a virus, it cheerfully accepts the mail (250) and then silently tosses it in the quarantine folder. If there is not a virus, it marks it permanently undeliverable (554) and sends a DSN stating that we don't accept any of a rather long list of extensions - you do block all 20-30 of the documented and undocumented executable extensions for Windows, right? So, with damaged viri, we end up sending lots of DSN's - wasting my server's time and innundating the poor spoofed sender. Thus, I would prefer that clamav be able to determine if it appears to be a virus, even one damaged to the point of non-existance. -- Daniel J McDonald, CCIE 2495, CNX Austin Energy ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users
