Pk, the error you are getting is not the one I would expect from those settings. Relay not permitted is the error I would expect.

Basically you are trying to send mail from smtp.hughes.net for accounts that are not provided by them. Normally the SMTP server simply rejects the send with a relay denied error, apparently Hughes just times out for some reason.

Why are you not using the registered mail exchanger for those domains? I know the godaddy service can be fairly poor, but your ISP it would appear is not going to play any more. You might get some joy in asking them, but I doubt it.
