Yes, it's the greedy match that's getting you -- I didn't think about that.
If you can classify the char that preceeds the email address (i.e. it's a
space or punctuation or either) then you can simply follow the .* with that
char or char class. However, if the email can come at the beginning of the
string, you'll have a problem.
HTH.

: Hmm. I like this more-concise method, but I only get the last
: character of
: the user ID rather than the full user ID. For example, I use this...
:
: REReplace(Target,".*(['_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-
: z0-9-]+)*\
: (([a-z]{2,3})|(aero|coop|info|museum|name))).*", "\1")
:
: ..on "[EMAIL PROTECTED]" and I get "[EMAIL PROTECTED]". Obviously, I'm rusty with RegEx
: but I seem to recall something about "greedy" RegEx pattern matching. Is
: this maybe the cause?
