Hello Aki,

thanks. I already found that options. I was trying also chatgtp to help me and it offered me:

mail_home = /var/maildir/%{user} mail_driver = maildir mail_path = /var/maildir/%{user} mail_index_path = /var/dovecot-index/%{user} mail_control_path = /var/dovecot-control/%{user}

The difference is the %{user} in mail_home. Should it be with or without it?

Thanks

Marek

 Hello Aki,

 sorry for doubling the question, maybe you missed it in the other text.
 The chatgpt told me to use mail_home = /var/maildir/%{user}, not
 mail_home = /var/maildir/. Does it make some difference? Or should I use
 your version? From my point of view your version seems better, but I am
 unsure of mail_home purpose.

If your mails *were not* in ~/mail, you obviously cannot use that, and you must use ~/ (if this was what you had before)

Hello,

When I changed it to /var/maildir/%{user} it started working. So apparently mail_home is the location where dovecot is searching the maildir.

Now I am uncertain what mail_path is then. I have set it to /var/maildir/${user}. Is it something wrong with that? Why should it be ~/mail? And what is ~ it is a users $HOME or the /var/maildir/${user} directory?

If I set it to ~/mail, should I create mail directory in the users maildir? What is the purpose of this directory then?

Oops, apparently it is not equivalent. When I changed mail_path from /var/maildir/${user} to ~/ my folders in a client immadiately disappeared. So I put it back and happy using. So it seems the ~ is the /home/username directory, not the one in mail_home.

Yes I reverted to mail_path = /var/maildir/${user} and I am happy with it. The passdb and userdb both make sense. It is probably by it.

this might be because you are returning home from passdb/userdb. Check doveadm user foobar output for more information and fix accordingly.
