We upgraded from Zimbra 4 to 5 so the value above was carried across without issue at that time but when I now try to put this new value (cluster11out.eu.messagelabs.com) into the 'Relay for External Delivery box', on the new Zimbra 5 Server, I get, 'Value did not match Valid value'.
I guess it's looking for an IP address instead of DNS name?
I know I could just put the IP address in instead but should I be able to put the DNS address in?
