Sendmail error replying

[Nejc Skoberne]

Zdravo.

Zanima me, kako prepricam sendmail, da mi bo vrnil sporocilo o napaki,
ce nekega userja na sistemu, ki mu skusam poslat mail, ni. Kje se to
nastavi? Gledal sem dokumentacijo, pa... nisem nic nasel.
Sendmail 8.11.2, ena masina, dobim tole:

Oct  3 16:28:26 Octopussy sendmail[14007]: f93ESQf14007:
<krneki at domena.si>... User unknown
Oct  3 16:28:26 Octopussy sendmail[14007]: f93ESQf14007:
from=<moj at mail.si>, size=0, class=0, nrcpts=0, proto=ESMTP,
daemon=Daemon0, relay=localhost [127.0.0.1]

Na nekem drugem strezniku, kjer mi stvar deluje, tudi Sendmail 8.11.2 pa
dobim tole:

Oct  3 16:03:38 aet sendmail[1111]: f93E3ck01111: to=krneki at domena.si,
delay=00:00:00, mailer=local, pri=0, dsn=5.1.1, stat=User unknown

relay=uucp at localhost
Oct  3 16:03:38 aet sendmail[1111]: f93E3ck01111: f93E3cl01111: DSN:
User unknown
Oct  3 16:03:39 aet sendmail[1111]: f93E3cl01111: to=moj at mail.si,
delay=00:00:01, xdelay=00:00:01, mailer=esmtp, pri=30869,
relay=moj.mx.si. [193.2.1.92], dsn=2.0.0, stat=Sent (Ok: queued as
8F28863BF9)

V cem je trik?

Res je, da je prvi .cf file verzije 9, drugi pa 8, vendar sem poskusal
tudi 9-ko downgradati a se vedno je situacija enaka.
