Thanks, but Im not even attempting to validate them at this point, I am simply trying to identify which TD pairs have emails in them to extract the addresses from the file. Its the only identifier I can even vaguely rely on......

Update from the pod:

item This module requires 5.005_63 or higher!

This module runs so slow as to be unusable with 5.005 stable. I'm not sure, but it might be because I build up my search regex using lots of compiled regexes. Either way, it runs orders of magnitude faster under 5.005_63.

that blows me out of the water for starters.....
