Just curious what the proper steps would be to provide my primary machine as a secondary MX for other domains. I found this:

http://wiki.zimbra.com/index.php?tit...aMtaMyNetworks

But I'm not sure if this is the only thing I need to do. Previously I had defined the other domains as relay domains in a postfix based system and added them to my_networks but is this all I have to do with Zimbra? or are there more config options that need to be addressed?

I'll keep digging but I thought I'd check just in case someone has the '5 step manual' of operations needed to make your Zimbra mail server a secondary MX for other domains
