Yahoo IMAP server - Rejected Password

My issue was only with iMac Mail... Not with iPad or iCloud. Mine resolved with deleting Keychain password and re-entering Mail account info in preferences. Sounds like your issues are more involved.

Also having this same, very annoying problem! A PAID alternative like Sparrow or Postbox etc. is NOT attractive to me when there are plently of FREE ones - like Thunderbird.

The Yahoo! IMAP server “imap.mail.yahoo.com” rejected the password for user “xxxxxxxxxx@yahoo.com”

Enter your password again or cancel.

It happens 20 times a day! If I enter the password - it connects and retrieves the email - and the settings and password saved in Mail are correct and verified. It works - sometimes.

I have repeatedly also tried the "remember this password in my keychain" tickbox.

The exact same IMAP requests/credentials from my iPad and cell phone work perfectly - without ever getting rejected. This tends to indicate it is NOT YAHOO'S fault.

I have run Keychain First Aid - no help there. It is a big problem for one Yahoo email account I have, and an occasional one on other email accounts as well.

If this keeps up I'm going to have to forget Apple Mail and go to Thunderbird or something else that's FREE!!!.

I think it is yahoos fault, because the default server for access on iOS is a POP server, different from the yahoo free IMAP server. I've been having thi same problem in Outlook for Mac 2011

Not sure if this is the problem. But when I tried to modify my existing setup from pop -> imap. I could not get my password to work. I ended up deleting the account from Mail and adding back. It works now. We'll see if I run into problems later.

Hope that works for you but I have done that many times with no luck.

Wish someone from either Yahoo or Apple would help us, this is driving

me mad. Good luck with it.!

Oh. Should also state I am still running 10.6.8. Haven't made the Lion leap yet.

I've had a Mac since October 2011 - always used MacMail and Yahoo (set up automatically on first use - no problems).

Since March I have been having the same error message IMAP Yahoo rejected your password?

I was told by BT to go to Yahoo web browser and go to options / accounts / save settings - don't change anything - this worked for a while, but am back to square one. I also upgraded from classic mail to, that worked for a day or two - bu now getting the same error - this is so annoying. BT wanted £30 to help me Apple wanted £35!!

This must be a server problem SOMEWHERE as it worked fine previously - PLEASE can anyone help us with this.

Same problem here - I'm also in UK - How do I look at the UK forum? - I have signed in and it bought me here??
