Sorry to butt in again, but mail from Viking to btinternet addresses is failing again, as before:
Delay reason: SMTP error from remote mail server after initial connection:
host mx2.bt.mail.yahoo.com [217.146.188.189]:
421 Message from (91.186.0.3) temporarily deferred - 4.16.50. Please refer to

Waste of time having a domain at all really, isn't it? May as well just stick to free accounts and dump them when they get spammed! Obviously, having a free yahoo account is as much a waste of time too!
