    I've suddenly run into a problem where Mail won't send -- to anybody.

    Error message: "This message could not be delivered and will remain in your Outbox until it can be delivered.

    "The sender address [my email address] was rejected by the server."

    The server, in this case, would be Time Warner Cable. But I can't think of any reason they would suddenly block me from sending mail while allowing me to receive to that address just fine. And the rest of my internet, including my Yahoo mail account, is up and running as usual.

    I think I may be looking at a corrupted application here. So my question is, can I do an uninstall/reinstall of Mail without completely reinstalling OSX (10.4.11)?

    Couldn't hurt i suppose... just depends on whether or not you want to continue troubleshooting or break out the Mac OS X CDs.

    I'm not sure what else to troubleshoot.
    I sent mail to it from my Yahoo accounts -- received fine.
    Tried sending to Yahoo accounts -- got error message.
    Tried sending to a friend on a different network -- got error message.
    Tried restarting Mail -- didn't help.
    Tried rebooting computer -- didn't help.

    What have i missed?

    Mail is owned by root. The only way for a user to corrupt the application is to enable the root account and use it for your day-to-day work. The standard way for MacOS X users to troubleshoot a misbehaving application is to create a new user account run the app from that account.

    You receive mail just fine. This means that your problems are limited to your SMTP (outgoing mail) server. This is where you need to concentrate your efforts. FWIW, there seems to be quite a bit of activity with ISPs hardening the security of their SMTP servers. This is probably at the heart of your "problem."
