We usually configure our MUAs to send e-mail via SMTP to localhost,
where Exim is running. This results in a header of the form:
Received: from localhost.localdomain ([127.0.0.1] helo=mydomain)
by myhost.mydomain with esmtp (Exim 3.33 #1)
id 1AdWvu-0005ks-00
for user@domain; Mon, 05 Jan 2004 16:46:22 +0100
Now, this seems to cause problems with some blacklists etc. on the net;
apparently they think "localhost" is evil.
Questions:
1. Why?
2. Is there a good way to avoid including this localhost reference? I
guess updatingreceived_header_text is a possible solution, but has
anyone done it?

3. Should I configure the mailers differently? Note that the ones we
are using typically don't allow mail to be sent via local (MTA
exec), and I'd rather not hardcode a hostname as I want the config
to be completely portable. (With the current setup it is e.g.
possible to move a host from the office LAN to a direct internet
connection, and send e-mail without reconfiguring anything - and
that's without transferring via the office when connected elsewhere.)
All this with Exim 3.34. (Yeah, I know I should upgrade, I'm just not
sure how to find the time to do the job...)
