Reverse DNS Exchange 2010
Posted on 2014-11-07
I have an Exchange server 2010 with multiple domains. The problem I have is some emails that go out would fail to a relay error. I have my ISP setup a reverse dns but even with that it still fails to some selected emails that end users send.
I tried to change my FQDN value i get a AuthMechinism on receiver connector error. Can I have multilple FQDN so when other email server check my SMTP banner it replies correctly? How is this all setup?
