Dear Joeyk,
The problem is that this error does not correspond to reality, I have already configured 3 types of emails.
Several ways and Mautic sends this message…
There is a way to disable this validation that is definitely inconsistent.
I copy and paste the data from my email hosting…
I configured everything on 08.09 it was working correctly yesterday when I went to do the email campaigns this error started to appear…
thanks for your time, have some solution.
