iMail problem on my MacPro

[Bob_Stan]

I have been using mail on my machine for over a month. I have 6 accounts set up. Suddenly today, whenever I try to send or receive mail, it asks me for the password, all of which have previously been saved to my keychain. However, even when I manually enter the correct password, it is rejected by the mail server. I access the same accounts with the same passwords from my Windows machine just fine. What could be going on? I have tried rebooting.

I have had this happen before sometimes for as long as a day or two. Seems to be a server side issue of some sort in my case since it always resolves itself without my entering new passwords.

I think you are right. After a couple hours it started working normally. What is strange is that during that period I could easily access my mail from a Windows machine. Thanks.
