I've been given the task of making our e-mail "more redundant". 
Basically, we currently have a single Courier server doing our mail 
storage, and serving smtp, imap, and pop3 in our main office, as well 
as to two (2) remote offices, and to several remote employees, 
travelling employees, etc. We'd like to cover the loss of our Internet 
connection.

I'm looking at putting a second Courier server for our domain in another 
office. My thinking is that the second (remote office) Courier server 
would "host" the users in it's office, while also having  rsync'd 
copies of maildir's from our main office server. The main office server 
would still host all other Courier users, and also have rsync'd the 
maildir's from the remote office.

This way, if the Internet goes down at either site, only Internet e-mail 
at that site is affected, whereas, currently, Internet downtime creates 
many problems (of course).

Crazy? Perhaps, but rsync'ing shouldn't cause any problems because of 
the unique file names, and it's --delete option should preserve the 
Maildir structure across to the "mirror" server, right? Our main office 
only has about 100 employee's, so the T1 bandwidth should suffice...

I'm setting up a lab to test everything, including name resolution, 
backup MX functioning, etc. and I'm also testing the switch to Active 
Directory for account lookup.

Thoughts? Ideas? Anyone done similiar?

Thanks,
jerry
