Problems in sending forms to emails

hi, my forms of incriptions in the website stay all in the box without go away to the e-mails

I have checked the email addresses you're using in your forms and I can see most of them are in our bounce list, this is the common reason for it: 

Reason(s) : smtp; 554 5.7.1 Service unavailable; Sender address

I have already removed them from our bounce list so you can receive emails now, please also check this guide that will help you to avoid bouncing related issues: How-to-Prevent-Email-Bouncing-Related-Issues

This other guide will help you to check and remove an email address from our bounce list, so if you're suddenly not receiving emails you may check it here and remove if the email is in our bounce list: How-to-Remove-Your-Email-Address-from-Bounce-List

Hope this helps.
