Re: question regarding 5.0.8 -> 5.0.11 upgrade

[Tom Golson <tgolson@tamu.edu>]

Somewhat off-topic, but do you mind me asking how your mail service is
presented to your customers?  We haven't enabled any of the proxying
that's generally available, now.  We essentially round-robin the service
behind a pair of F5's and then rely on the redirect behavior of Zimbra
if you log into the wrong mailstore.

We were looking at the 5.0.15 update but this bug
http://bugzilla.zimbra.com/show_bug.cgi?id=35893 made us a little
nervous.  Have you looked at this?
