Suddenly, our queue is stacking up with undeliverable mails (few hundred overnight). Below is a snippet of log file which is typical showing MX connect fail or Stack Connect fail. Ran DNS report on some of the domain names trying to be delivered and apparently showing that no reverse DNS on all that I checked. I did implement some of the rules.ima Chris and Rick shared but do not see anything in there that would be causing this. Help as our server now timing out often! Thanks.
