OK, done that. That has cleared all my mail boxes. I ran through new account set up and it has sent a test email to my other account fine.
Thank you very much for your help.
Thanks for the reply. I tried that and got:
The connection to the server smtp.ntlworld.com on port 587 timed out.
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be delivered.
Connection Doctor tells me...
I have set up a POP email account to forward mail from my domain. I get emails fine, but can't send them. I have the correct Smtp address which my isp (virgin media) gave me. I don't really understand the ports. Is there something obvious that I am missing here?
