I've deployed a script to do a number of scans based on what kind of file is uploaded, i.e. if it's html, do certain checks to protect against uploading phishing webpages. if tarball or exe, run antivirus if plain text, run it past a regular expression to see if they are uploading a huge list of email addresses. 
$filetext =~ m/(    [\w\-._+]+   #first part of email address
                    \@[\w\-.]+   #second part
                    .{0,5}       #any char/separator
                )   {50}/sgmx

of course, on files with 100+ email addresses, this thing loops like crazy. I understand *why* perl is tripping out on it somewhat, but I don't know what to use to fix it, or as an alternate method. now that I think about it... I could probably use grep... Anyway, and suggestions are appreciated. mC
