I have set up 2 accounts on Outlook - and can receive email on both, but cannot send on either. I have disabled the windows firewall, and still have the difficulty. This is the notification I receive:
Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:
'emaderios@yahoo.com' on 2/14/2008 1:25 PM
550 relaying mail to yahoo.com is not allowed
btw - yahoo.com is not exclusive. it doesn't matter what domain I try to send to, all are stopped with the same error code. When I spoke with the IT guy at my company, he thought perhaps it was the firewall, so I turned that off - and tried again, getting the result you see above.
PLEASE, PLEASE, PLEASE HELP
