Hi,

Using exchange 2013 server using EDGE 2013 for outgoing email flow. We are not getting any delivery failure message notification when we sent an incorrect email address.

====== Edge server message tracking details====

ConnectorId             : EdgeSync - Default-First-Site-Name to Internet

Source                  : SMTP

EventId                 : FAIL

InternalMessageId       : 7683696492577

MessageId               : <1900e46b6fc246ce9305a3e9a235567b@servername.local>

Recipients              : {mraffi22222@xyz.com}

RecipientStatus         : {[{LRT=};{LED=550 #5.1.0 Address rejected.};{FQDN=};{IP=}]}

Any help? why no delivery failure for this incorrect email address?

Hi 

By default the message expiration time out is 2 days.

If you want to change follow the link

See if you can view those messages in the queue 

xyz.com is a valid email domain and they may have configured the option not to send a bounce back for a user who is not in their directory. This is to compact phishing attacks.

Try a domain which is not valid at all.
