[Solved]Owncloud doesn't send the invitation e-mail

I’ve installed Dietpi, to use Owncloud, on a raspberry pi zero w, and now I would like to create some new users.

The problem is that the system does not send out the initiation e-mail, and in this way, I can’t create them.

I think the problem is in the SMTP configuration since I never configure one. But I’m not sure.

Can someone tell me how to solve this problem?

Thanks in advance

even without mail configuration you should be able to create new user and set a password. The message about not being able to sent mails could be ignored I guess.

That’s true.
It works also without sending out an e-mail.
I’m wondering when someone forgets the password, how she/he can manage it…

depends how large your installation will be and who is going to use it. If it is your family mates only, you could do it as admin I guess.

That’s true…
Since is a family cloud I’ll avoid the e-mail system.
Thanks again
