Hi,
a friend asked me to convert a qmail system to an exim3 system, i was a
little bit limited and couldn't use ALL posibilities to make the config
clean and simple (no embedded perl, and no exim4). He wanted to use the
default exim-package of debian, and so i only could use the features they
provide. I hope someone is interested in this config, and maybe someone
has some ideas to make the config a little bit nicer. I'm not a qmail
expert, nor a qmail user at all, so i created everything by the
information he provided me.
This config is no in production use yet, i stripped out some things, that
are not needed to be explained.
If some qmail-expert finds an error in this config please contact me.
If you are interested, i could rework this for exim4, where some things
could be done in other ways, and the rewrites for ./Maildir and &email are
not needed anymore.
P.S. Thanks to Phil (again) for this wonderful MTA, that makes all this
possible ;)))
