Hello !
I use a script for my computer backups.
Recently to change the smtp to be that of my plesk. But I have an error.

When I go back to my OVH smtp, no mistake.
I think it's my SMTP plesk that has a problem. Do you have an idea ?
Knowing that I go through port 587.
Thank you very much because it's been a week since I've been here, and I can not see where the problem comes from...
