Dear Pros,
I am using postfix-2.3.3-2 on CentOS 5.2.
a. There is a valid domain called example.com.ex with a valid MX entry
b. There is another domain called example.com withour a MX entry (both can
be for same company or for different)
Now when a user tries to send mail to u...@example.com.ex, its is successfully
delivered.
But when a user tries to send mail to u...@example.com, even though it cant
find the valid MX entry for this, still it is trying to send mail to the IP
address which is resolved from example.com because of this the sender is not
getting any error message and this mail is there in the mailq for a long time.
("connection refused" error message can be seen in the output of 'mailq'
command).
The sender think that, the mail is successfully delivered, eventhough the
reality is vice versa.
1. Is there any way to configure in postfix that, if he didnt find MX record
for a domain even after (say 3 or 5 times) then postfix has to stop the
processing of that mail, and send a error message indicating the MX problem to
the sender.
2. Is there any way, to notify the sender the status of the message (other than
sent). For eg;
a.. if a message sent successfully no need of any report or notification.
b. if a message is in deferred queue, it should send a notification to user
that, this is in deferred queue due to so and so issue (may be MX, may be
network timeout, etc) and will try to deliver it in a later time.
Any guidance is really appreciated ;
