In comp.mail.misc you write:

Standard? You talked about configuration, which must
meet your local requirements (or am I wrong?).
I think there is nothing standard in configurations.
My experience told me that is much simpler to maintain
a centralized mail configuration, not a distributed one.
This way you have to maintain only few "mail servers"
and do a little on the other nodes. I mean, for example
you have to work hardly on few hosts to configure/maintain/etc.
and have a simple and possibly equal configuration
on the other sites. I think this fact should be clear.
Using centralized configurations you have to configure/etc.
at least two hosts, one for backup in case one goes down,
and do some Name Server config/maint. (in case you're working
with Unix). BTW, what kind of systems/platforms you plan
to use?

We are actually switching to a new domain. Since the number of
hosts we're planning to connect is high, it would be a suicide
to maintain/configure/etc.. every site with a distributed solution.
In part we have switched to a centralized solution and we will
convert totally after the switching will be finished.
I replyed to the group because I hope that could
be intereseting to open a discussion on this - it
interests me too :-).
