Subject: Urgent help needed!! / Fwd: Undelivered Mail Returned to Sender

Date: July 4, 2020 at 9:20:00 PM ADT

To: CCN Office <office@chebucto.ns.ca>, CCN Office <userhelp@chebucto.ns.ca>

Dear Chebucto Community Net, 

It is a urgent problem, I found there are countless such emails (please see below) sent to my Chebucto account (taiji@chebucto.ca), since this afternoon 2pm, now it becomes every second receiving this email and have been hundreds of them.   

I just called Mr. Shahab Rowshan, he suggest me to send a screenshot and a sample of such email to you.  Would you please help to stop those email sending to my “taiji@chebucto.ca”?   

Now it has over 600 of those similar “undelivered final returned to sender” emails sent to my Chebucto inbox, and it is not stopping at all, still keeps coming.   While I have not used this “taiji@chebucto.ca” email for a long long time.  And have not sent any emails from this taiji@chebucto.ca account for a long time already.  

Look forward to you urgent help, please 🙏 🙏 

Yours

Yau-Sun Tong 

Halifax
