I am trying to use a master user. The login works. However, a LIST command gives me only the INBOX. Is this to be expected? When logging in normally, I do get the full list of folders.

Your configuration is somehow wrong then. Set mail_debug=yes and look at the logs to see where Dovecot is trying to find the mails from. If that doesn't help, post the log, your dovecot -n output and other relevant configs.

It logs the correct value for "home" with mail_debug=yes. It is also able to print the correct quota values, so Dovecot seems to end up at the right place.

My test PHP program is here:

echo '<? $mbox=imap_open("{localhost:143/notls}","am*master","masterpw", OP_HALFOPEN); print_r(imap_list($mbox,"{localhost:143}","*")); print_r(imap_get_quota($mbox,""));?>'|php -qC

The log looks like this (with domain changed to example.invalid):

It was actually auth_debug that I turned on, not mail_debug. Here is the mail_debug log. It led me to suspect the acl plugin and, indeed, if I turn that one off, I can list the folders even with a master user login.

Cheers, Anders.

Hi Timo,

do you have an idea about this problem? To summarize, I cannot list folders if using a master user login and the acl plugin. (my dovecot -n output was in the message before the one quoted above)

Thanks, Anders.

With master users ACL plugin uses the master user for ACL checks instead of the mailbox owner. That also makes the default ACL be "deny" for mailboxes.. I'm not sure if there's currently any other simple way to avoid this than to disable ACL plugin for master users.

Okay, I disabled the ACL plugin for master users by creating a global .DEFAULT acl file:

==== user=master lrwstiekxa owner lrwstiekxa

Was that how you meant?

Thanks, Anders.
