Apple Mail does not work after new server move
I was recently moved from server 75 to server 190. After changing the settings on my iPhone, it seems to be working there. But when I change the settings on Apple Mail (secure190. ...) it refuses to send email. I changed it back to secure75. yesterday, and was able to get it to send there, but now neither server works. And starting this morning, it looks like incoming mail is reaching my iPhone but not my MacBook. How can I fix this?
