I should have pointed out that each parsing and validation generates numerous arrays and string objects, including one call to preg_match() and one call to eregi() each. Also, we should eliminate string concatenation from header construction and use a nested output buffer instead. At one occurrence per mail_send(), this isn't too much of an issue, but with multiple cats per address, this could be a big issue. In any case, it's an easy way to squeeze out more scalability. ~joe -- DokuWiki mailing list - more info at http://wiki.splitbrain.org/wiki:mailinglist
