Pre-Authentificated Sessions ============================ For debugging purpose or to perform IMAP actions on-behalf of an user, one can use pre-authentificated sessions. Simply, one calls 'dovecot --exec-mail imap' and can speak IMAP via STDIN. However, the call does not always populate all environment variables and one needto setup the uid and gid /before/ the call, hence, the name "'PREAUTH'". Secondary, the call does not drop privilegues in-the-middle, therefore someaccess permissions, such as to log to a file, may fail. In this case, one canuse an alternate configuration file. So a more advanced call might look like this: ---%<------------------------------------------------------------------------- sudo -H -u user /usr/local/dovecot/sbin/dovecot \ -c /usr/local/dovecot/etc/dovecot-cmdline.conf --exec-mail imap * PREAUTH [CAPABILITY IMAP4rev1 ...] Logged in as user ---%<------------------------------------------------------------------------- Note the 'PREAUTH' in the reply. Now one can speak IMAP. The part 'sudo -H -u user' sets up the uid/gid for system users, one might need 'sudo -u vmail USER=user HOME=path' for virtual users.
