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,
