Zazzle : All emails sent come back as fatal error

Hi,

After several months of hard work on my Zazzle stores,
I was trying since a week to send emails to Zazzle support team.

However, for unknown reasons, all my emails I sent to Zazzle provide me an 'Mail Delivery Status Notification (Delay)' message saying that Zazzle support team email address 'had fatal errors'.

Also, I would like to know if there are other Zazzlers in BHW who presently encounter the same issue.

Thanks in advance,
