Hmm, good point. This is the sort of reason for my asking before I leap... > [I've genericised @w-c-f.org.uk to @your-domain in the following, > strangely easier to type] Of course I would have preferred wcf.org.uk but it had already gone :-( > As I see it, there are two options for the mail: > 1.

The latter, so in fact I'm not receiving mail as w-c-f.org.uk anyway... > 2.

Yes I had thought of that > (So many ways...) .. to get it wrong ;-) Thanks to both of you, I'm clearer now: I think there's no real need to rename. It would be a little tidier, e.g. Outlook Express, as well as stripping the trailing space off my sig separator :-(( gives email message id's of xyz@tower.localdomain instead of 123@simon.w-c-f.org.uk, but it's only a nicety Incoming and outgoing mail should work alright (indeed are doing already as I haven't done any renaming) A tinker with majodomo.cf and the associated aliases should sort out the lists. Might cause me dns work if I rename. Cheers -- Simon Child
