mail.app not connecting to ISP
I have Monterey OS 12.4 on my desktop Imac and have had problems with email--also on my iphone. When I try to send from the Imac, a box pops up saying "Can't connect to the account "Mcttelecom.com". Then "Enter the password for user (and my name)." I enter my password and response is: UNable to verify account name or password.
On my iphone, I have to choose to send from my icloud account to get anything mailed. I can send to my usual non-icloud address.
From my Ipad, the icloud account return address doesn't work, only my regular non-icloud account that nothing else accepts works.
Logging into my ISP from the web works fine so I can't figure out why the mail.app won't take the same password.
I've reset all my passwords in account preferences and they are all identical. ISP no help here.
Thanks for any suggestions. I tried to rebuild the mailbox but nothing whatsoever happened.
