the answer to that question heavily depends on your configuration.
Because of that I can only give you a pointer to where to start.
You need several imapd.conf files (name them any way you think is
appropriate), each of them having different authentication settings -
e.g. if you use SASL SQL auxprops
sasl_sql_select: SELECT %p FROM mail_user WHERE user='%u' AND
realm='%r' AND imap=1
or something similar.
In case you want people to be able to use webmail, you will need a
private imap service that's only available to the webmailer - e.g. on
localhost. The config for that service must be set in a way that
everybody can login.
Then create different services in cyrus.conf that specify your config
# add or remove based on preferences
# services (INTRANET)
imaps cmd="/usr/local/bin/imapd -C /etc/imapd-imap.conf -s"
imap cmd="/usr/local/bin/imapd -C /etc/imapd-imap.conf"
imap-webmail cmd="/usr/local/bin/imapd -C /etc/imapd-webmail.conf"
pop3 cmd="/usr/local/bin/popd -C /etc/imapd-webmail.conf"
Hope that helps,
