Hi George, BT probably blocks use of SMTP outside of the UK as a security measure against Mailboxes who have been compromised. They might have to use gmail or such like for SMTP and their BT for incoming, not ideal I know. only thing I can think of. Regards, Barry.

An associate in the Canaries can receive e-mail, but is unable to send. Both POP3 and SMTP servers, which work here OK in the UK, are set to "mail.btinternet.com". Any suggestions as to where to begin looking?
