What SHOULD happen is that the second bounce (the double-bounce) gets sent to postmaster@ instead of the invalid user. So in your case it should look like: Spammer forges [EMAIL PROTECTED] to [EMAIL PROTECTED] random.foo bounces "User Unknown" to [EMAIL PROTECTED] client bounces the bounce to [EMAIL PROTECTED] Now, if someone's bouncing postmaster mail I'm not sure what will happen. > If it does then there must certainly be a way to stop it, such as > silently dropping failed mail. You can configure a custom delivery address for double-bounces. In some places I've used this in the sendmail.mc: dnl # Drop all double-bounces. dnl # Either supply an address (postmaster) or null string to drop. define(`confDOUBLE_BOUNCE_ADDRESS', `')dnl I'm not sure what this translates to in .cf syntax. It's something frightening, I'm sure. - -- Matt Brodeur RHCE [EMAIL PROTECTED] http://www.NextTime.com Hard work has a future payoff.
