Exchange Mail Server - MTA poor reputation? Not on blacklists. Just set up PTR
Posted on 2011-03-09
I have suddenly encountered a problem where the mail from my exchange server is being rejected due to poor reputation. The server is at exchange.healthone.com.au
The server/IP does not appear on any black lists and all seems ok.
Until 24 hours ago, I did not have Reverse DNS set up, but this has never been a problem before. I now have the Reverse DNS (PTR) record in place, but this does not seem to be helping.
