Hi,
Our edge server seems to delay emails sent to some domains without an DNS/MX record. For example emails sent to a gmail.com.au account will be delayed instead of rejected. It appears to be related to the fact that @gmail.com exists.
____________________________________________________________________________________________________
Delivery is delayed to these recipients or groups:
user@gmail.com.au
Subject: test
This message hasn't been delivered yet. Delivery will continue to be attempted.
The server will keep trying to deliver this message for the next 3 days, 19 hours and 53 minutes. You'll be notified if the message can't be delivered by that time.
___________________________________________________________________________________________________
However, if the domain does not exist at all it does reject them:
Diagnostic information for administrators:
Generating server: xxxxx
test@fnidsncoindscoid.com
#554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##
__________________________________________________________________________________________________
It appears that it will delay emails sent to any @domain.com.au if the @domain.com exists. This is means that end users are not provided with instant feedback that they are inadvertantly attempting to send to a wrong email address. Anyone dealt with this issue previously? Any advise assistance would be appreciated.
