It seems that the symaptico.ca email addresses have been changed. Especially if your address was @sk.sympatico.ca, bc.sympatico.ca or ns.sypatico.ca
I wasn't aware of these changes and only found out because so many newsletter updates were bouncing from these types of addresses.
If you used to have a @xx.sympatico.ca or just @sympatico.ca and now have a different address please login to the 'Member Profile' page and update your contact emaill address.
In fact that is a good suggestion for everyone who reads this to check their contact information and update it if nescessary.
