I don’t have this problem with my Mac mini - just my iphone7 - not sure maine.rr knows how to help. I can’t get their support to function for me - no idea why

Why can't your email provider help you out with their own email product, that doesn't make sense.

Apple has no clue what your credentials are for that account only your email provider does.

Contact them and explain the issue, a quick google search shows their moving on to spectrum.

Start by contacting your maine.rr support or looking at their help forums.
