Hi.
In my postfix queue I can see messages with return code 5xx which are still in
queue for delivery.
I find this strange, as the RFC 2821 states that codes starting with 5xx is a
permanent failure, and "The SMTP client is discouraged from repeating the exact
request".
Is this default behavior, or is this something I have done in my config by
mistake?
An example from the mailq:
653001005C5 1832 Sat Nov 16 09:17:26 ikkes...@netthandelen.no
(host mta5.am0.yahoodns.net[98.138.112.32] said: 554 delivery error: dd This
user doesn't have a yahoo.com account (qaram...@yahoo.com) [-5] -
mta1500.mail.ne1.yahoo.com (in reply to end of DATA command))
qaram...@yahoo.com
and this one:
624BC100599 1974 Sat Nov 16 00:01:31 anonym...@dist.kundeportal.no
(host spam.bitpro.no[92.42.64.205] said: 550 5.1.1 <postmas...@fiko.no>:
Recipient address rejected: undeliverable address: host
mail.bitpro.no[92.42.65.67] said: 550 5.1.1 User unknown (in reply to RCPT TO
command) (in reply to RCPT TO command))
postmas...@fiko.no
Why is postfix still trying to deliver these messages? Can this behavior be
changed by configuration?
