Thanks for the reply Ray
The reasons for trying to achieve something may be blurred but I have a network where the internal domain is domain.tld
domain.tld is also a registered domain and email gets handled accordingly
the problem I get is usually with
www.domain.tld where it is housed remotely
now thats ok, until the hosting company moves it
SME forces either delegation to another server or A records
CNames are a way of managing this
The situation is actually more complex than this, but hopefully you get the drift.
The problem with my solution is it doesn't display the records in the SME Admin area.
