Using an admin account to authenticate is not a standard feature supported by all imap servers. Sometimes it is implemented via the --authuser1 option, sometimes not. It depends on the imap software server and its configuration. You have to follow this road: * Determine what is the imap software server * Find out whether it supports an admin account or not * If no, leave this reading, take an handkerchief and cry * If yes, search how the imap software server supports an admin account (see below) * Figure out whether an admin account is actually configured or not, * If not then configure it. If you can't configure it: handkerchief. * Finally, check an imapsync authentication via this admin account for a standard user, the option --justlogin is nice for doing this. * Use it for all users. * Next, read their email messages, enter their personal life etc. I'm kidding.
