I'm looking at adding an MTA to my current Zimbra install to help move the external email processing off the mailbox store/web interface.
Right now the main Zimbra server is running Zimbra 4.0.5 on RHEL 4.
I know I'm going to want to setup the MTA with exact same version of Zimbra.
I was wondering if it would be fine if I installed that on RHEL 5 or if I would need to install it on RHEL 4 as well?
Thanks for any help or information!
