We have a firewall, and would like to let users outside the firewall access the Zimbra server through the proxy. (Proxy server sits outside, passes connections in, and all is well.) IMAP/IMAPS and HTTP/HTTPS installed and are working just fine, but I can't find anything in the documentation that tells me how to get SMTP/TLS proxified through.
A quick search of the forums got me this post (http://www.zimbra.com/forums/adminis...roxy-smtp.html) but not an answer.
It almost looks from the documentation like I should be able to install Zimbra MTA on the proxy server, and have it deliver to the stores without running the MTA on the store itself - is that the correct answer here, or am I missing something obvious? (Multiple-Server Installation)
