Sender's address isn't

Hi,

We have several RT installations some years now, and everything has
been working fine. We have recently installed a RT 3.6.0 in a client,
and we’ve seen a strange behaviour: the Sender: header in outgoing
emails is defined using a strange hostname (it doesn’t even exist, and
we don’t know where RT got it from).

This week we installed a fresh copy (to test RTFM, etc) in a completely
different machine, different setup, etc. and the problem is the same.
Every outgoing email whose sender is Nobody: has the email address
nobody@show.HOSTNAME. Any clue on where this “@show” is coming from?

The relevant configurations are these:

Set($MailCommand , ‘sendmail’);
Set($SendmailArguments , “-oi”);
Set($SendmailPath , “/usr/sbin/sendmail”);

I’ve even tried searching RT’s base directory (grep -ri “@show”), but I
can’t find the right button to squeeze.

Thanks in advance,
Ricardo Oliveira

Likely it’s not RT but sendmail inserting that Sender address.
