To give some context: If you run your own mail server, you have the ability to view and analyse log files.
As far as I know, with a SaaS mail server you can't see delivery or bounce messages from sources.
You have no idea if a sender mail server is on a whitelist, even though the server is on a spam list - only because of “backroom conversations” between an inner circle.
I was told by a customer that he had no chance to deliver mails to a large service provider because his sender IP was on a spam filter list. It took almost 10 days to get the IP off the list.
2 weeks later, the customer told us: we are not receiving any mails from the service provider. Because we use the same spam filter lists, the mails were rejected because the service provider's mail server was on the spam filter list.
Because the service provider didn't care, we had to lower our shield to receive emails from them.
It's unfair just because of the flies and shit.
Some are equal some are more equal.
