If my box would take mail for non-existent accounts it would have to bounce them to the envelope-from, not some <ident-response@whereever>. That has nothing to do with ident. Take one of my mails to debian-user as example: Received: from ka.graffl.net (someone?else@193.154.165.8) by murphy.debian.org with SMTP; 25 Jul 2001 23:24:41 -0000 Received: from WatchZwerg.waldner.priv.at (none_of_your_business@WatchZwerg.waldner.priv.at [193.80.224.98]) by ka.graffl.net (8.9.3/8.9.3/Debian 8.9.3-21) with ESMTP id BAA08314 for <debian-user@lists.debian.org>; Thu, 26 Jul 2001 01:24:38 +0200 The only source of mails to "someone?else@193.154.165.8" or "none_of_your_business@WatchZwerg.waldner.priv.at" are spammers, but such clueless ones usually also try to send mails to the message-id... But of course sendmail does the right thing (it´s not exchange or bloatus notes), it never even stores mails to unknown accounts, it just issues a 5xx ("no such luser") in the smtp-conversation and that´s it. rcpt to:<someone?else@[193.154.165.8]> 550 <someone?else@[193.154.165.8]>... User unknown rcpt to:<none_of_your_business@WatchZwerg.waldner.priv.at> 550 <none_of_your_business@WatchZwerg.waldner.priv.at>... User unknown cheers, &rw -- -- My name is sendmail.cf. -- You killed my process. -- Prepare to vi. ----
