None of your e-mail accounts could send to this recipient

I posted this message in a related group, but there doesn't seem to be much
traffic there, so here goes.

I recently moved and got Comcast as my ISP. Their default setup is with a
wireless router, which gets me reasonably good throughput times (1632 kbps
down/356 kbps up, according to DSL Reports). However, at least once a day,
and always the first time that I send mail through Outlook 2003 after
starting the program, outgoing messages are rejected as undeliverable, with
the note "None of your e-mail accounts could send to this recipient." If I
go back into the "Sent Items" folder and re-send each item, they will
usually go through fine. I'm guessing that there is some time-out setting
that needs to be tweaked here, but I have no idea where to look for it. Any
ideas?

You should check your server settings with Comcast. If they are OK, make sure
your network connection is made before you start Outlook. Don't put it in
your Startup group. Wait until everything is loaded and all lights are
blinking happily, then use the Quick Launch or Desktop shortcut to Outlook to
start it.

Done, done and done. I've checked the settings with Comcast to see if
they're optimzed, and they are, I have good up and down connect speeds as
verified by DSLReports, and Outlook isn't in the Startup group. I don't
start Outlook until the machine has started fully and stabilized.
