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. -- Sahil Tandon <sa...@tandon.net>
