Me neither. I have been running e-mail server for so long, that I
really don't care about these "blackbox" solutions. They are more
trouble than they are worth.

EMC storage if you have the cash.
AFS if you don't.
NFS is as unreliable as it gets.

Yeah, the bastards :)
Actually, as long as you have a sound base system (qmail, exim, postfix,
even zmailer), and someone with a few years experience, you can always
get a good system.

Actually, .forward provides intra-MTA routing instructions, not delivery
instructions :)
I agree "nothing to do" was a little strong worded, since everything
has to do with local delivery. That is, after all, what the whole
e-mail system is about.

Yup. You can even use it to do most things people usually do with
amavis. I have a server where I implemented individual message size limiting,
so each group of uses will have a different limit, entirely based on
exim filters.
Of course, exim is monolitic, so I would not say it has its own filtering
agent. It has a filtering system :)
Actually, you can do almost everything you get from procmail with
exim filters. I'm just used to write procmail rules, and have
a huge database of those, so I keep using it for the sake of
simplicity (and not reinventing the weel).

Nah. No one started screaming yet, or even compared us to Bryan. So
we still have some room :)
