You use reject_unknown_recipient_domain, which results in a
deferral and
re-retry of mail delivery in the case of *temporary* error.
Postfix will try
to deliver the mail until $maximal_queue_lifetime. Set
$delay_warning_time
to a non-zero value if you wish for Postfix to send the envelope
sender a
notice that mail was undeliverable, but is still being re-tried.
To understand the difference between your two scenarios, try using
host(1) to
query yahoo.com.uk and talktalk.com.

Aha! Now I understand - thank you to you both (Michael and Sahil).
Running host on them both shed a lot of light. I'll look at
$delay_warning_time so it warns me if I do it again...
Thanks.
