I have run the server.sh script on all of my servers but the job queue does not change. (Just realized the browser covers the 4th server, it has the same output as the other 3.)

The first 2 of those servers don't have a A record set, it seems. Your mailservers probably can't access your master server, so they are not updated. Or you installed something wrong, and the mailserver(s) are using the wrong database (a local database instead of the one on you master for example)
I have set an A record for the first two servers. Also, I have verified that the 2 mail servers are using the correct mysql server, and that a connection can be made to it from them.
127.0.0.1, with its port set to 4076 because I use an ssh port forward/tunnel from the master server to the mail servers for security. [root@smtp1 ~]# cat /usr/local/ispconfig/server/lib/config.inc.php | grep dbmaster $conf['dbmaster_type'] = 'mysql'; $conf['dbmaster_host'] = '127.0.0.1'; $conf['dbmaster_port'] = '4076'; $conf['dbmaster_database'] = 'dbispconfig'; $conf['dbmaster_user'] = 'secret'; $conf['dbmaster_password'] = 'secret'; $conf['dbmaster_new_link'] = false; $conf['dbmaster_client_flags'] = 0; As said in my last reply, I have verified that I can access the master database from the mail servers by running mysql -u myuser -p -P 4076.
