Return Mail Notice

Hi

When you receive a email on the mail server with this type of notice Oct 9
00:05:18 shell sm-mta[28005]: ruleset=check_relay, arg1=[71.113.162.178],
arg2=127.0.0.4, relay=pool [71.113.162.178] (may be forged), reject=554 5.7.1
Rejected - see http://www.spamhaus.org. 1) Does the server send a notice back
to the sender? (2) If so, how can I tell sendmail not to send these types of
email notices back to the sender please?

Here is my sendmail config

Never fails to amaze me just how little IT admin know these days and yet get jobs.

That is the message that is sent back to the sending server. You can shorten
the message to just rejected but you are required by RFC to send the
rejected=554. If you don't you could get listed as a idiot.

So you could do...

FEATURE(`blacklist_recipients')dnl FEATURE(`dnsbl',`sbl-xbl.spamhaus.org',`554
Rejected')dnl

However, I still say that even removing the reason why is only going to piss
off every postmaster you *will* get hate mail for doing so.

What do you mean by "send a notice"? *Your* sendmail does *not* generate
an e-mail message (i.e. "bounce") and send it - the error text is given
in response to commands given by the remote server (i.e. 71.113.162.178)
in the SMTP session. If that is a legitimate server trying to deliver a
message, *it* will generate a "bounce" e-mail message (hopefully
including the error text) and send it to the sender. If it's a spambot,
it'll likely just drop the whole thing on the floor.
