AbleCommerce Shopping Cart Software

Error-
Error sending email with subject 'My Wishlist'. Mailbox name not allowed. The server response was: sorry, the sender name and auth login doesn't coincide (#5.7.1)

On the "send wish list page" this is whats in it. I think some of this stuff is coded in the software that I cant get into. I may not know what I am talking about but thats why I have you guys,.

<div class="pageHeader">
<h1 class="heading">Send Wishlist Link</h1>
</div>
[[ConLib:SendWishlistPage]]


Now my theory is that this page comes up with my email in the from box. The software allows the user to change it. Maybe if the user changes it, it causes the error. In fact I will test it.
What do yo know!
I changed the from email and it failed. I didnt get the email from the wishlist and got the error at the exact time I tried to send it.

So is there something we need to change so it doesnt error or to disable where the user can change the FROM email address.

I found this thread

We did change ours to require authentication because we were having problems with emails getting blocked or blacklisted. Then again i only know what I am told and not why I am told it

Found out that if the from address is mine it works. But the customers email is populated into the from address and thats when it fails.

Error sending email with subject 'what i want for christmas'. Mailbox name not allowed. The server response was: sorry, the sender name and auth login doesn't coincide (#5.7.1)

The problem is with your mail server. Your mail server doesn't allow SMTP outbound if the FROM address doesn't match the SMTP authentication credentials used to send the email.

Configure your email settings so that the SMTP authentication credentials match the FROM address on your wishlist email template. So if your email template (or store email address) is set to "noreply@<mydomain>.com", your mail server email settings, SMTP credentials must use the login name of noreply@<mydomain>.com.
