Roundcube Webmail is a browser-based multilingual IMAP client with an
application-like user interface. It provides full functionality
expected from an e-mail client, including MIME support, address book,
folder manipulation and message filters.
This plugin lets you impersonate another user using the dovecot master user feature.
WARNING: please only use for user support or similar operational issues. I recommend
you always get approval. Using this without consent may be illegal in some countries.
For more information about this feature read: http://wiki.dovecot.org/Authentication/MasterUsers
The default separator character used is '*', but you can set a different one using the plugin config file.
