Not sending e-mails for contacts but Test e-mails working

My Mautic version is: 5
My PHP version is: 8.1.26
My Database type and version is: 10.6.16-MariaDB-cll-lve

My problem is: I get an error message when trying to send e-mails to contacts

These errors are showing in the log:
Fail to send e-mail to redacted@gmail.com: Expected response code “250/251/252” but got code “553”, with message “553 5.7.1 redacted+bounce_65a57fea0cf77434600398@redacted.com.br: Sender address rejected: not owned by user redacted@redacted.com.br”.

Steps I have tried to fix the problem: I revised the E-mail Configuration, SMTP - all seems to be ok - tests e-mails are being sent normally.

Usually this is due to trying to send outbound email from an address which isn’t on your approved senders list.

Double check that as a starting point!

Hey! Thanks!

How do I do this approval senders list process?

Also I found that my Mautic doesn’t have this section bellow:

my Mautic is like this:

Hi there,

Your first screenshot is from Mautic 4 or earlier. The second is Mautic 5.

I’ve flagged that up for the education team to review.

It depends which email service provider (ESP) you’re using, but for example here’s the docs for Amazon SES:

I was facing the same issue error 553 5.7.1. Its there when you fill IMAP configuration in configuration > email settings. Although “Test connection and fetch folders” is giving success message. Try removing IMAP configuration clear all the text boxes related to it. Installing the setup on shared hosting web installation(using the zip file) might be the reason for this.
