So I set up the postal SMTP server using a test domain of mine, but it disrupts the site (“connection is not private”). How can I connect the smtp server to my domain while it still being made available to the public (not disrupting the site). If my site already has a subscriber list and email, how can I create my smtp server around it? Lastly, to build the reputation of the smtp ip address, what is the max amount of emails I can send with that one ip when I eventually build it up? Because I thought we have to rotate multiple SMTP’s to get to 50k and above per day, but doesn’t rotating the smtp’s disrupt the reputation building process?
