When i try to send a email from my PHP app i get this message '550 Mail from domain is not allowed from your host'.

Can someone help me please.

Is it possible to have a backup interval for each apps, like i have one app (nexcloud) very heavy and take a lot of time and ressource to backup and send to GCS, so i would like to put this app backup one a week and all the other one a day.

Thanks.

My nextcloud has get down during the night, so i try to repair it this morning, but it was in pending so i try to uninstall and reinstall from backup but both are in pending since 3 hours, how can i repair ?
