Hi,
I installed Exch 2013 and is working great - both incoming mail and outgoing mail work fine in OWA and outlook.
Problem we are having is SMTP authenticated relay. We install application on all client computers which sends emails externally/internally.
Though we had authenticated in application, we are not able to send emails externally. Internally it works fine from application.
Our backup software stopped sending notifications on failures. Literally we are logging into each and every server and making sure backups are successful.
We never had a problem with Exchange 2010
I don't want to create relay and allow my whole ipaddress range (I think that's stupid)
Can anyone please help?
