Unfortunately it's actually not that easy. It involves remembering a matched substring across *two* rules, which ATM SA does not provide any mechanism for. Devs: there've been wishes for this before; how hard would it be to add the ability to match on the substring match captured by another rule? Add a flag to say "capture the match for this rule" and a syntax for substituting that into the match RE of another rule, and dependency enforcement? In lieu of that, if you're familiar with Perl you could write a plugin to do what you suggest, or you could do something externally to generate three rules per known user (or known valid email address) on your system: one indirect for the To, one indirect for the From, and a meta to AND them. You could do it in sendmail.cf -- John Hardin KA7OHZ http://www.impsec.org/~jhardin/ [EMAIL PROTECTED] FALaholic #11174 pgpk -a [EMAIL PROTECTED] key: 0xB8732E79 -- 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- The yardstick you should use when considering whether to support a given piece of legislation is "what if my worst enemy is chosen to administer this law?" ----------------------------------------------------------------------- 9 days until Bill of Rights day
