In control panel i'm using (plesk) has the dns records displaying, everythhing seems to work fine except www prefix.. ie webmail.maindomin.co.uk
could you point me in the right direction where to look for the setting on my system command line.
also some back ground the domain in question has been backed up from one server using plesk backup and transfered to another.. it may be an ip mapping problem from what iu've read but find it difficult to investigate (cause it's a little beyond me
