I am going to structure this in the following way.
Primary box -
accept incoming e-mail's for organization, users will be connecting via
Pop only. All e-mail will be removed from the server and downloaded onto the
users PC. I do not need console/telnet mail for my users, only the root
account for convenience (I am flexible what program I will use). This box
needs to selectively relay e-mail based on network address. (or if possible
authenticate the sending user). I have 50 local users, and 40 remote users
(these numbers grow quickly). We maintain mailing lists for the different
office locations as well as the different departments.
Secondary box -
just in case the primary is down. This box needs to accept e-mail and
relay to the primary, as well as selectively relaying based on network
address. This machine will also host some announcement mailing lists. The
lists have a large amount of users but are low volume.
Both machines will be a Dell PC w/ a 400MHz celeron processor, 96MB of ram,
and a 6GB hard drive.
We connect to the Internet via a full point-to-point T1.
Mailstats from the current Linux/Sendmail machine (no office or external
mailing lists are running on this box) are in the attached file.
I need to provide LDAP to my users as well. I have been reading from
http://www.openldap.org but will take a while for me to understand the
config. This is not a big concern.
I intend to install a web interface to the mail system in the future, again
I have not done an evaluation yet so I am really flexible to the
configuration.
Thanks for the help
- Max

Insufficient data.
Just to answer the maildir question, we need to know something about
how the system will be used. Will all mailbox access be via POP or
IMAP, or will some users log in to read mail using pine/mutt/etc? If
the latter, will these people also need POP/IMAP, or will they
exclusively use a local MUA?
Some MUA's don't grok maildirs. E.g., pine requires patches. Mutt has
excellent maildir support. For POP/IMAP users, maildir works well.
For other configuration options, we'd need to know more details of
your set-up. It's probably best to go with a basic configuration and
tweak it as necessary.

Raise concurrencylocal and concurrencyremote. Run dnscache.

qmail-pop3d. There are imapd patches for maildir support. See:
