<Servername #5.7.1 smtp;550 5.7.1 Unable to relay for Destinary email>
So im having this problem for many month and it goes and comes to all users in the exchange server.
I check all the relay setting on the virtual SMTP server, we add the domain, the server ip, the IP of the computer of the user and nothing.
We only used exchange mode in outlook, the problem happen for other emails account and from OWA too.
Today i had it, what i did restart the server, delete all ips in the SMTP virtual server and add it again and it work, but i know it will stop again.
Maybe exchange goes crazy and forgets the relay setting, i really don't know what can be the problem.
