macid @ mcmaster.ca is an email alias that, by default, points to your Muss email account (
[email protected] ter.ca). However, if you decide to change/set your Primary Email Account using Mugsi, that alias will then point to your new primary email account. It happens overnight, not right away. macid @ muss.cis.mcmaster.ca ALWAYS points to Muss although you might choose to forward your email from there.
Undergrads can view or change their primary email account by following these instructions
