[Pkg-mailman-hackers] Bug#303342: A different solution for Exim4 integration

[Roger Lynn]

I use the Exim configuration documented on the Exim website at
http://www.exim.org/howto/mailman21.html

It seems to work well and I think it looks cleaner than your suggestion. I
thought it looked more up to date and superior version supplied by Mailman
upstream.

I use a GID of "daemon" as that is what the README.EXIM.gz file supplied
with Debian Mailman has always instructed.

I don't understand why you're using MTA = "Postfix", as it seems to make
things more complicated and all the documentation says to use MTA=None with
Exim. (Is it so that the Mailman domains can be set in mm_cfg.py instead of
in the Exim config?)

Could these files be installed automatically by the Mailman package, as
suggested by Tollef in
http://lists.debian.org/debian-devel/2005/02/msg00965.html ?

I assume that mm_domains could be made to default to the contents of
/etc/mailname. For most users I imagine that it might be possible to remove
mm_domains altogether, and replace it with local_domains. Better would be if
it could be set from something like /etc/exim4/update-exim4.conf.conf, but I
don't suppose that would be possible without a nasty hack?

The priority of each file is worked out from the description in the Exim howto.

Hope this helps,

Roger
