We have a zimbra server that works fine in house.
The problem we are having is with user authentication in conjunction with a barracuda spam appliance.
The spam appliance is where our MX record points, so all mail goes there first, gets scanned, and if is legit, comes to the zimbra server.
The barracuda is supposed to check with the zimbra server to see if the incoming mail matches a real user on the zimbra server...user verification?
It appears to not work. The barracuda is having troubles talking with zimbra.
I hope I'm explaining this right.. Has anyone had any issues like this?
It looks like the spam appliance isnt verifying with the zimbra server correctly.
We've switched the spambox from RCPT to VRFY and that still doesn't work.
