Almost. They're checking his envelope-from address, which is available in the Return-Path header and that, if differs from the From address, some MTAs, or some configuration of them, will add to the purely-informative Sender header. :-) Cheers, -- Adeodato Simó dato at net.com.org.es Debian Developer adeodato at debian.org Q: How do Debian developers play Russian rulette? A: Everone contributes a key revocation certificate and chooses a number from one to ten. Then everybody executes a random generator - if it's a match, then his revocation certificate is submitted to the keyservers. -- seen on [EMAIL PROTECTED]
