Can't send mail through Comcast. Any ideas?
Before anyone can provide any meaningful ideas, you need to supply some meaningful information.
1. Are you trying to send using webmail from a browser, or from a standalone email client on a PC (or some other device)?
2. If it is from an email client application, what email client are you using, and what are your outgoing (SMTP) server settings?
3. Are you getting any error, reject, or bounce messages? If so, what do those messages say?
