There was some networking work performed that broke my outbound email flow due to an unexpected IP address change. Email queued up during the equipment install as expected with dsn=4.7.5 or dsn=4.0.0 codes. Two days later one of our external vendors returned a dsn=5.7.1 which caused Postfix to remove the email from the queue since this is not a temporary error. From my reading of the documentation everything is working as designed. Am I overlooking a setting or options to modify this behavior so email will stay queued even when we receive a permanent error so that we do not lose mail again if something similar happens?
Yes, this is as expected. Permanent 5xx errors remove mail from the queue and generate a bounce to the sender address.
To override this behavior, see http://www.postfix.org/postconf.5.html#soft_bounce -- Noel Jones _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
