Sujet: [Exim] Virtual domains, on one host

I'm trying to setup virtual domains, all on one host, and I need to make
sure that the To and From headers don't get touched at all once leaving
the MUA. I haven't been able to get this to work so far - it seems like
the headers are being rewritten to the primary hostname of the machine
doing the hosting.

I'm fairly certain that outgoing mail gets modified, I'm not entirely sure
about incoming at this point.

I'm runing the Debian/potato distribution of exim, with a hand modified
config file, though I'm not sure that I've changed anything significant.

I've looked through sample configs, and tried *some* of the virtual
hosting stuff, but it doesn't appear to have worked quite the way I
expected it to. (It also hasn't solved my header rewriting problems,
which is the biggest problem right now.)

Here's a sample header that I just tested from a separate machine:

Date: Sat, 18 Dec 1999 19:09:55 -0500 (EST)
From: ryan@???
To: ryan@???
Subject: test

that was address to ryan@??? when it left Pine on the other account.


One related question: With a director like
virtual:
driver = aliasfile
domains = "lsearch;/etc/exim/local-host-names"
search_type = lsearch*
no_more
file = /etc/exim/$domain-aliases

If I put a line like "*: ryan" in the alias file for a subdomain, does
that reroute *all* mail to anyone in that subdomain to the user ryan on
the local machine? If I other users that want to get mail in that domain,
but I want anything else to go to a specific user, how do I do that? Is
it easily possible?


Here's the config file I'm using. (I cleaned out some comments in the
process, I'll be more than happy to send that version if it's wanted.)

Thanks for any/all the help you can give, I'm planning on writing
something that explains this all concisely when I figure it all out, so
that it can be easily added to the FAQ. (I read the FAQ, and nothing
seemed to quite cover this situation, or, at least didn't *obviously*
cover it.)
