Postfix Error Server 4.0
After upgrade getting the following error:
fatal: the Postfix mail system is not running
warning: not owned by _postfix: /Library/Server/Mail/Data/mta/./guid_device_maps.plist
Tried changing ownership but it reverts on startup of mail services.
I can connect to the server via telnet and local mail but nothing external is connecting.
Mac Pro, OS X Yosemite (10.10)
