I know this should be an easy question and I promise I've looked around for the answer.
I reinstalled my server. I did a massive upgrade to a different server and I wasn't smart enough to read ahead before I blew away what I had.
Anyway, I remember setting up SMTP+SSL on, obviously, port 465. In fact, I don't even remember needing to set this up. Now, I'm trying to get everything back to normal and this is the last part of the Zimbra config that I need to get going again.
Wow, that's long winded... How do I make Zimbra listen on 465?
