Question

Cannot receive .mac e-mail  on my two older Macs running Mail 2.1.3 on  OSX 10.4.11 since the last weekend.
Still sends mac.com e-mails and all other "non mac.com" e-mails on "Mail" are working fine incoming and outgoing?
Cannot access via i-cloud on 10.4.11 as told not supported and cannot update for old I-mac as later OS not suitable for processor on imac
Works OK on Macbook air with current OSX
HELP.....Please??

IT WORKS!
Though it doesn't tell you this in the password error message, the problem IS the new Apple ID password requirements. 
FIRST go to https://iforgot.apple.com/ and CHANGE YOUR PASSWORD.  In my case, my old password didn't use at least one capital (upper case) letter, and that was preventing the whole thing from working.  When all the little password criteria lights are green, you're good.  Save as you exit your browser if it asks you to.
Then open Mail, preferences, accounts, and click on the plus sign to create a new account called iCloud Mail.
These are the settings I used:
Account settings:
Description: iCloud Mail
email address:  [email protected]
Full Name:  John Doe
incoming Mail Server: imap.mail.me.com
User Name:  John Doe
password: (enter new Apple ID password)
Outgoing Mail Server (SMTP): smtp.mail.me.com
Server settings:
Server port: 587
check box Use Secure Sockets Layer (SSL) yes, check it
Authentication:  Password
User Name: [email protected]
Password: enter new Apple ID password
Click on Advanced tab:
Check "Enable this account"
Check "Include when automatically checking for mail
ignore Compact mailboxes automatically
Check Automatically synchronize changed mailboxes
IMAP path prefix: leave blank
Port: 993
Check Use SSL
Authentication: Password
Be sure to save the settings when asked after you close the accounts window.
O.K., this little part may be a complete coincidence, but in mail, nothing happened when I hit "get mail".  Then, when I clicked on the little "broken" icon on iCloud mail on the left, it sprang to life and imported all my mail from iCloud.  However, as I say, that may have been unnecessary and a complete coincidence of timing as I had hit "get mail" previously.
If that doesn't work, try shaking dried chicken bones tied with cat gut over your machine.
Best of luck!
