I have new Ubuntu server with Dovecot installed, with Roundcube frontend, with root access.
And an inbox on third party service (web hosting + own domain pointed there by setting DNS addresses), without any server access, I just have credentials to Roundcube and IMAP/POP3/SMTP settings. I don't even know which protocol is this mail using (both all allowed).
How can I import all mails from this third party service inbox to the Dovecot? (i.e. mirror my mails to Dovecot, then point my domain to the new server).
