Apple Mail Failure with Yahoo Mail
I've tried to search but find only irrelevant threads.
Perhaps since installing Monterey 12.6.1 update I have had continuous failures to obtain complete emails from my Yahoo accounts. Sometimes the emails are truncated and sometimes there is no message content at all. When I first setup my Yahoo accounts on this MBP late 2021 running Monterey 12.6.0, all emails from Yahoo were complete.
I find using the Mailbox> Rebuild> option gives quite imperfect results. The partial emails and emails with no content change from rebuild to rebuild but the Yahoo inbox is filled with incomplete emails each time. Those that are partial and those that have no content at all change. I find I'm rebuilding my Apple Mail, Mailbox 10, 20 or more times a day.
I've tried deleting my Yahoo account to no avail. I've tried deleting all accounts and a bunch of preferences in Library folder related to Apple Mail in an attempt to reset Apple Mail. Nothing so far has worked.
There are no problems with emails that are truncated or with completely missing content on this computer when using Mozilla Thunderbird or Web mail with Safari, Brave and Firefox.
I've tried to change my Yahoo account over to Pop3 hoping once an email is downloaded to this computer complete it will stay that way but I've never gotten Yahoo Pop3 to work.
I really prefer Apple Mail on this computer but I'm forced to rely on Thunderbird for all Yahoo accounts.
