From Distributed POP3/SENDMAIL farm servers to Zimbra

[andresu]

Hello everyone,
I´m planning to migrate to Zimbra
I actually have a scenario with example.com , and two separate linux servers located in different cities.  There are high mail internal traffic and slow link beetween the servers, so actually the servers operate :
- External mail is received trhough Fetchmail -- this step are OK and tested with the Zimbra new server and works fine.

- Two servers handles internal mail to "example.com"
- There are different users in server "A" and users in server "B", but same domain example.com
- Server "A" routes mail to users in server "B" using Sendmail-Forward aliases and viceversa, using Domaintable feature.
I´m intended to mantain the same structure. Two servers separated fisically but managing same domain, different users.
What ZImbra Wiki articles, or how-to can  read to do this?
Thanks and regards!
