I think below regex matches everything up to @ sign.
/(bounce.*@)/i it does NOT check anything after @ sign. This is WHAT I NEED something like these. nore...@bounce.domain.com nore...@bounce.com Be exceptionally careful of ".*" [It very, *very* often matches more things than you expected it to.] I can't think of a specific example of a line that would cause an issue, but your regex, will match something like this too. [Essentially anything with "bounce" with anything in-between, followed by an "@" later in the same line. blah blah blah ji...@bounce.com fre...@someotherdomain.com blah blah blah @ blah [In this case, it will match on the second "@", not the first - as an example of how .* works.] or blah blah blah ji...@somedomain.com freddy-bou...@someotherdomain.com blah blah blah or blah blah blah ji...@somedomain.com fre...@someotherdomain.com bounce blah blah blah @ blah Any new regex, I'd monitor it carefully for some time to be sure it does what you expected it to do, especially if it has a .* in it. -Greg
