I have a couple of minor problems with this upgrade. The first is a bounced email that was a reply to a message in my inbox, the message:
Code:
3FD9932423F: to=xxxxxxx@dsl.pipex.com, relay=smtp.he1.systems.pipex.net[62.241.163.97], delay=25, status=bounced (host smtp.he1.systems.pipex.net[62.241.163.97] said: 504 LOCAL: Helo command rejected: need fully-qualified hostname (in reply to RCPT TO command))
Nothing has changed on my server apart from the upgrade to this release of Zimbra, I do have a FQDN and hostname returns the correct name.

The other problem is in the Admin gui, on the Global Settings/MTA tab if I change one of the tick boxes then hit save I get:

Code:

If I try this a couple of times then Zimbra will lock with the 'clock' timer visible.

What other info do you need for these problems?
