I have a customer that has a Microsoft Exchagne 2016 Server which following an upgrade of an internet line from ADSL to Fibre is having real issues sending and receiving emails from GMAIL and Yahoo.
We have fixed some issues by getting the ISP to allow Reverse DNS (some of the rejection notifications pointed to RDNS being the issue), however there are some other delivery and receipt issues that just wont seem to go away!!!
I would like to have this resolved and the Exchange Server given a bit of an MOT.
