Might anyone know why I can receive comcast mail via Mozilla Thunderbird, but can't send email from Thunderbird? I'm running Thunderbird V3.1.10. The error message is....
Sending of message failed.
The message could not be sent because the connection to SMTP server smtp.comcast.net timed out. Try again or contact your network administrator.
Any help would be appreciated

Which port are you using for smtp? Do you have SSL on or off?

From JR's instructions for Thunderbird setup:
Outgoing Server (SMTP):
Server Name: smtp.comcast.net
Security and Authentication
Use name and password is checked
User name: my Comcast user name
Use Secure Connection: TLS button is selected (this is special for Thunderbird).

Big thanks to each of you for sending a response. My configuration matches what was provided by you all. However, it still isn't working.. I can't seem to post the screen shots.

What anti-virus program are you using? Is it checking incoming/outgoing mail? If so, you can turn that part off as both incoming and outgoing e-mails going through the Comcast e-mail servers is put through virus scanning by Comcast.

Ugh - any other ideas? Should I be able to ping smtp.comcast.net?

UPDATE: Finally Successs
Set SMTP server config as follows:
Port = 25
Connection Security = STARTTLS
Authentication = No Authentication
Set Server Setting/Security Settings as follows:
Connection Settings = None
Authentication Method = Password Transmitted Insecurely

Yes, port 25 use doesn't require authentiction unless you are outside the Comcast network, like at a hotel or hotspot somewhere. Also, many people are having port 25 blocked by Comcast at the cable modem, so I highly recommend you to switch to 587, STARTTLS, and simple password authentication.
And no, smtp.comcast.net does not respond to ping.
