SYMPTOMS
When you try to send an e-mail message, you may receive the following error message:

'Sending and Receiving' reported error (0x8004210B):

'The operation timed out waiting for a response from the sending (SMTP) server.

If you continue to receive this message, contact your server administrator or Internet service provider (ISP).



CAUSE
This problem may occur when you are connecting to the Internet through a Linksys BEFSR41 router, a Linksys BEFSR81 router, or a Linksys BEFW11S4 router. These routers have Maximum Transmission Unit (MTU) problems that may cause timeout errors when you send e-mail messages.



WORKAROUND
To work around this problem, change the router's MTU setting to 1492. For information about how to change your router's settings, visit the following Linksys Web site:
