It looks like your mailserver ist trying SASL authentication when
sending out mail. What's the output of these commands:

  postconf | grep smtp_sasl_
  postconf | grep enforce_tls

Try setting $smtpd_enforce_tls and $smtp_enforce_tls to "no".

Your users are sending mail using cemc.math.uwaterloo.ca as their
smarthost: when sending mail to email@hidden the mail is delivered
from their local system to cemc.math.uwaterloo.ca and from there to
mail.example.com. The second step fails, because cemc.math.uwaterloo.ca
tries to use SASL authentication without being able to supply username
and password.
