If my box would take mail for non-existent accounts it would have to
bounce them to the envelope-from, not some <[EMAIL PROTECTED]>.
That has nothing to do with ident. Take one of my mails to debian-user
as example:
Received: from ka.graffl.net ([EMAIL PROTECTED])
by murphy.debian.org with SMTP; 25 Jul 2001 23:24:41 -0000
Received: from WatchZwerg.waldner.priv.at
([EMAIL PROTECTED] [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 "[EMAIL PROTECTED]" or
"[EMAIL PROTECTED]" 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:<[EMAIL PROTECTED]>
550 <[EMAIL PROTECTED]>... User unknown
rcpt to:<[EMAIL PROTECTED]>
550 <[EMAIL PROTECTED]>... User unknown
cheers,
