You've already answered both your questions:

- the whole error message you quoted is obviously coming from Eudora, 
since that's what presented it on your screen for the pleasure of your 
reading.

- the actual transaction error that Eudora is telling you about -- "550 
5.1.2 <name@domain.com> ... Unsupported mail destination" -- is coming 
from the Rogers SMTP server you're trying to send through (note the 
"SMTP server says").

Based on a googling for "5.1.2 unsupported mail destination" and the 
subject of the first result, my guess is that Rogers is running postfix 
and will not allow relaying unless you are using authenticated SMTP.

I'm not familiar with Rogers policies these days, but a couple of things 
to check:  are you sending the mail via your Rogers connection (vs. at a 
friend's or someplace else)?  are you using plain SMTP or authenticated?  
are you able to send to another @rogers.com address (i.e. is it only 
non-rogers.com addresses which fail)?
