> They no longer accept mail from servers they haven't seen before.
Interesting. This tracks with my experiences too, but is there a good source for this that I can reference in the future?
I got out of hosting email last year entirely because of intractable deliverability problems with the big three: Google, Microsoft, and Comcast. Comcast's issues mostly appeared intermittent and the result of incompetence. Google and Microsoft have clearly been competing to see who can kill small email service providers the fastest.
I contacted Microsoft, actually received an answer from them and got an IP unblocked.
Google can be tough though. If their Algorithms don't like you, good look.
I was responsible for a new IP/Email setup and while all other relevant providers liked our mail and Google Postmaster tools didn't show anything bad, all our mail went to Spam in GMail. I found out why when even mails from completely different senders would usually go to Inbox but hit Spam once our Website or email was included:
Despite showing it as "high reputation", GMail must have considered it as utter trash. Changed to a different, older domain and all has been fine since.
How did you contact them? I had problems getting mail to MS years ago and at the time wasn't able to get anyone to do anything or even respond. At some point later the problem went away, though.
