Hi everyone,
I run some mass-mailing servers with Postfix 2.11.3.
I have some messages being deferred because of malformed addresses
like "john....@gmail.co" ("gmail.co" instead of "gmail.com").
gmail.co exists, but does not answer on port 25. Postfix correctly
treats this as a temporary error and will return the mail to sender
after $maximal_queue_lifetime. From postfix's point of view, this
is indistinguishable from a domain that is temporarily offline.
That's the point, sender never gets notified about non-delivery.
I checked my config and see that I never had
"reject_unknown_recipient_domain" in my restrictions. Could it be the
cause ?
I added it and will see what's going on after 5 days of queuing.
