Basically that the accounts are active, have plenty of quota (or unlimited). Maybe as Michael points out it's due to some special chars in the name but I doubt this.
Can those user's send a message to themselves? Do those user's use IMAP(another thread on how certian IMAP clients may deadlock the server)? Does a restart of tomcat and postqueue -f allow the queue to clear. If a tomcat restart clears it then the next time it happens please get a thread dump of tomcat "kill -QUIT <tomcat pid>". Then zip and attach the thread dump to a post from /opt/zimbra/tomcat/logs/catalina.out
You also may want to look in catalina.out for exceptions on those accounts related to mail/LMTP delivery.
