[ZendTo] Issues with sending to external users

In your "From:" header, do you really have a space between @ and zendto?
From: Zendto <no-reply at zendto.XXXXX <mailto:no-reply at utoronto.ca>>
That would do it, for sure.
And you appear to have stray spaces in the To: header as well. Any/all
of those would break it.
And have you set the value of "EmailSenderAddress" in
/opt/zendto/config/zendto.conf?
Cheers,
Jules.
