Hi, I haven't had any issues with Shopify emails until today (28 Oct 2020).

I can't communicate with my customers via Shopify email, the email bounces back .....

This is the mail system at host

I am having the same trouble with emails.

The response from the remote server was:

554 5.7.1 <>: Recipient address rejected: user does not exist


Address not found
Your message wasn't delivered to julie@juliedavisveach.combecause the address couldn't be found, or is unable to receive mail.



Did you receive any guidance or have you resolved your problem?
