Description of my issue

Error: "500"

Action: "PUT" /yunohost/api/services/dovecot/start

I have access to yunohost, but I cannot access my e-mail address. There is such a service error, I am sharing the log.

There’s a lot of errors there about a user “Vmail” not existing. Is this a user that you removed recently?

I actually reinstalled yunohost I think that’s what you’re talking about
