.mac Password not accepted in Mail?

Question

I've had my .mac email set up on my iMac for several months and 2 days ago I got a message when Mail was checking for new messages that my password was not accepted and for me to re-enter it. Ever since then it has not accepted my password. Why would it do that all of a sudden and how do I fix it? Mail is setup to remember passwords.

Answer 1

I have my Mail app set to check mail every minute but it does not ask
me for my password that often.
When having the Mail.app check the account for new mail every minute and if there are a number of messages to download and/or a single message contains a large attachment or a number of attachments and the communication with the incoming mail server is not completed and closed for whatever reason before the next automatic check for new mail, you will be prompted to manually enter the account's password instead of being provided a proper error message indicating there was a problem communicating with the incoming mail server.
Change the automatic check for new mail to every 5 or 15 minutes instead which should resolve the problem.
To each his own but I have no need or desire to have my email accounts checked for new mail every minute. Checking for new mail every 5 minutes should be plenty adequate.
