First build a generic Liferay email hook, ShellHook.java, that shells out all of the email methods. You install it by adding these lines to portal-ext.properties: mail.hook.impl=com.liferay.mail.util.ShellHook

mail.hook.shell.script=/usr/sbin/mailadmin.ksh

mail.box.style=INBOX

We next built a generic Korn Shell Script, mailadmin.ksh, that implements each method for Dovecot, or any other email system you want. It supports an interactive command line interface for testing:

mailadmin.ksh --help

mailadmin.ksh

mailadmin.ksh addForward [userId] [emailAddresses]

mailadmin.ksh addUser [userId] [password] [firstName] [middleName] [lastName] [emailAddress]

mailadmin.ksh addVacationMessage [userId] [emailAddress] [vacationMessage]

mailadmin.ksh deleteEmailAddress [userId]

mailadmin.ksh deleteUser [userId]

mailadmin.ksh updateBlocked [userId] [blockedEmailAddress]

mailadmin.ksh updateEmailAddress [userId] [emailAddress]

mailadmin.ksh updatePassword [userId] [password]

All of the code is in SVN. mailadmin is at: mail-ejb/scripts/fedora/ksh/mailadmin.ksh Here are the step-by-step installation instructions:
