Dear All,
Today I have received the email from IRCC Permanent Residence Confirmation Portal ask to confirm my email and current address in Canada etc.., however, my online PR application status shows "We are processing your application. We will send you a message when there is an update or if we need more information from you. "
I am a bit confused, could you please confirm some of my doughts listed below.
1. The email address is genuine " 
IRCC.ClientPortal-PortailClient.IRCC@cic.gc.ca ?
2. does I only need to reply to this email to confirm my email address only?
3. IRCC will send me an email to open the Client portal login information?
Thanks and best wishes
