Zimbra support - very glad for their help
Just want to share that over the past month or so we've gone through a gradual transition from a single server to multiserver environment. We had a couple of minor issues along the way and one major issue (today). Until this transition, I haven't had to contact support much over the years we've been with Zimbra, but when I have needed to they've always been very knowledgeable and helpful.
In each of the cases I've needed to contact Zimbra's support staff they've been able to assist. When we had a complete outage, they were on the phone with me very quickly.
So my thanks (and thanks on behalf of our faculty) to William L, Rick K (and anyone else at Zimbra who has helped out that I can't recall the names of).
