Hello. New member here. Long time Zimbra client user, brand new Zimbra installer/admin.

I've now installed Zimbra 5 times and spent 4 nights working on this. I've reached a dead end. Everything seems to go smoothly on my install and then, after a reboot, Zimbra seems to stop listening to IPv4 traffic. Using the lsof command, I can see where it's listening to all the normal ports (IMAP, SSL, Admin, etc...) on IPv6, but they're not on IPv4. I don't run an IPv6 network.

I followed each step (or I think I did) of the install guide from this forum (thank you!). I found instructions on modifying my zmmta.cf file to make it work with all networks, but that didn't seem to change anything.

I've searched for IPv4 and IPv6 in the same posts on this forum and using Google. Apparently I don't know what to search for.

Can someone please offer me a suggestion on what I've done wrong or what log files I should post to show what's going on?

Thanks!

Jeff
