"The yahoo.ca IMAP server “imap.mail.yahoo.com” rejected the password for user (my email address)" ...

WTH does this mean?
Ever since I added Yahoo! Mail to my Mail account, it always pops up and makes enter my password. How do I get it to end, please?
Thanks.

unfortunately this kind of thing can happen sometimes. i get it with my sympatico account from time to time, and usually just respond by hitting cancel and then taking the account back on line after a couple minutes which usually works. there are a bunch of posts out there like this one:

one thing to try is deleting the password in your keychain and then launch mail and enter it fresh when you get prompted. you can also try changing the frequency of how often mail looks for new emails, sometimes having it do the 'every minute' check can create problems.
good luck!

I've had it happen a few times. It tells me I'm using the wrong password. I'm not but I'll the message a few times in a row as I try it again and again. Then the next time it works. This is all in one session of trying to log in to mail.

it's annoying.

If I drop Yahoo! from my Apple Mail option, does it still show up on my iPad and iTouch? Or are they linked to the Mail account on the Mac?
