Hello all, I am wondering if anyone knows of any resources that may recommend potentially unsafe file types that should be blocked (or explains why certain file types should be blocked in e-mail). I am running GFI Mail Essentials and out of the box it is very restrictive. I have relaxed many of the blocks. There are a couple that I have questions about and would like to get the communities opinion. Should these be blocked? - .ASF - .WMV - .MPEG - .WMZ I realize that most of these deal with video in some capacity, but my concern is if files of this type can in general be safe to my user community (free of virus') Thanks for your opinion, Chris
