Got a minor problem and don't know where to begin looking. I've checked DNSBL lists for the IP of the server and it's free, not on any lists anywhere.
For some reason emails from my domain are not getting through to a list of about 200 people when we send out emails. I don't get ANY bounce backs at all! The list is about 700 people in total. We send out about once a week to this list, most of them are getting the email, but around 200 of them are not.
At this point since we don't get any bounce backs at all and the IP is not blocked I don't know where to go with it. Are there a lot of internal lists and anyway to check those?
We are talking scattered emails like Yahoo and Juno nothing set to one main server. Then there are a bunch of individual domains.
