This is a fairly common problem.  It is most common with users who
have Comcast as their ISP.  It is due to a timing issue between Mail
and certain ISP's.  Mail gives your account password before your ISP's
server is ready for it.  When the server is finally ready for it, the
password has already been given, and the server must request it again.
There is a potential work-around for the problem here:

"...[go] into the Keychain application, located in the Utilities
folder. In the upper left column, highlight "log-in." In the lower
left column, highlight "passwords." In the right window scroll until
you find your "mail.comcast.net and smtp.comcast.net" or whatever your
internet service provider incoming/outgoing mail servers are called.
Double click on each which will bring up an attributes/access control
window. Select access control. Then select the bullet next to "allow
all applications to access this item." Make sure you do this for both
the incoming server (mail.comcast.net) and outgoing server
(smtp.comcast.net) keychain items. "

I also highly recommend turning IPv6 off.  As a side benefit, doing so
will more than likely result in a noticeable speed boost to your Web
browsing.

If you are running OS X 10.4 (Tiger):
Go into System Preferences --> Network --> go to the "Show:" dropdown
menu and have it show Built-in Ethernet -->
TCP/IP tab --> Configure IPv6 button -->
change the setting from Automatic to Off.

If you are running OS X 10.5 (Leopard):
System Preferences -> Network -> choose the Ethernet tab in the far
left column --> Advanced button -> TCP/IP tab --> Configure IPv6:
droptdown menu, choose Off --> Okay button.
