Just a suggestion (I'm not a sympatico user) - try "robert" by itself (drop the @sympatico.ca) and see what happens.
No luck, the test failed.
I did find using using one of Sympatico's real old smtp server names worked.
For those having difficulty using email with Sympatico try changing the SMTP server name from smtphm.sympatico.ca to smtp1.sympatico.ca. Worked for me. Go figure!
