Reverse DNS does not match SMTP Banner
Posted on 2014-11-09
We recently moved office locations. AT&T Uverse was our last ISP. Now it is Logix. We have an Exchange 2013 Server that we moved to the new location. I updated the WAN address and contacted Logix to request they setup a Reverse DNS record. That fixed my Reverse DNS bounce back problem I was getting. However, now when I go to MX Toolbox and run the diagnostics it tells me that my Reverse DNS does not match SMTP Banner. I have Googled and searched thru the Receive Connectors and the only thing I see is that in the connectors my FQDN shows up as PCSI-ADEX.pcsitx.local and I think my banner is showing mail.pcsitx.com I tried to change the FQDN to mail.pcsitx.com and it wouldn't let me. It gave me an error. I didn't have a problem with this at the old location. Can someone tell me how I go about fixing this issue? Thanks so much!
