Recently I am not receiving notifications from my order form

Not sure if something changed with the form...I was receiving email alerts when orders were placed using my order form.

Hi,

Your email address was automatically added to our bounce list because your host started rejecting the notifications from us, giving the following reason:

Reason(s) : smtp;550 No Such User Here"

We can easily remove you from the bounce list, and our server will start sending out notifications again. However, there is an underlying issue as stated by the 'reason' above.

Kindly contact  your hosting support for further help on that matter to prevent the problem for reoccurring in the future.

Thanks!

Neil
