You can anchor regex to the BOL or EOL, meaning the search for match will only be applied to the the BOL or EOL data. As opposed to non-anchored regex will will scan every single byte, say, in your 30 meg mpeg porno clip. what's nice about blocking by .ext of the attachment, you don't have to scan entire attachement. >is that for scanning non text based email or specific to imgate stuff? It's Regular Expression stuff. Unix is very strong in text processing tools, and the foundation is the regex lib's built into the OS, or into language like PERL. I don't know if Scott has put full regex support into his products, and I'm pretty sure Imail's pattern searching is not full regex. anyway, one should try to match on headers or attachement type or file type of the attachment, since the scanning target is small and fast. Only as last resort, scan the entire body. In fact, if you conclude that you can only block by scanning the entire body, then you're probably sscrewed, unless you have tons of surplus computer power to waste on full body scanning.
