I use postfix relay smtp server. Rarely send senders to a faulty email address but not send a notification to the sender that the address is wrong, only the letter is in the mail queue.

766AA2133F 46933 Sat Jan 12 19:44:40 from@nobody.tr (connect to mail.somebody.tr[203.188.141.10]:25: No route to host) wrong-email-address@wrong-domain.tr

Why doesn't the sender be notified? which postfix to use for the solution ? thanks, Steven

maximal_queue_lifetime (default: 5d) Consider a message as undeliverable, when delivery fails with a temporary error, and the time in the queue has reached the maximal_queue_lifetime limit. Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). The default time unit is d (days). Specify 0 when mail delivery should be tried only once.

Resolution:

postconf -e 'maximal_queue_lifetime = 1d'

thanks for the help, by
