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 Expected response code “250/251/252” but got code “553”, with message “553 5.7.1 Sender address rejected: not owned by user”.

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!
