OK I am stupid please help me?

[Katymac]

I have several email accounts with BT (one main account & 4 sub accounts)

3 sub account behave fine

1 doesn't - it won't accept emails from the other accounts

It all looks the same on properties etc

I have obviously broken it

Can anyone fix it?

no idea, but I can give you a bump

Thanks

Can you give us any more clues... what did you fiddle with??

Well I have actually worked out that this email has never sent to the other one

Gosh I am daft aren't I

All the sub account get mail from outside but one won't send to one of the others (but it will send tyo all other sub accounts)

I am a pratt aren't I
