Hi everyone…I used to manage a ton of mail for my work and moved on quite a while ago, but now I have the desire again to centralize mail services. I’ve got the obvious (Gmail, Yahoo, etc.) providers covered, but I’ve always wondered if there was a more unified list of official traffic rules (connection limits, messages per time, etc.) for mailbox providers anywhere. If not, I would be open to making it and perhaps a good base config for documented limits / requirements from mailbox providers as well as supplemental recommendations for others.
I’m basically starting over on this information and hoping someone might have recommendations, a start, or maybe I’ve just missed an awesome resource over the years.
Thanks in advance for any help you can offer.
