    Default changed domain name and IP address, now can't relay mail through ISP's mail server

    I already had a mail server (cyrus) running for my domain, kaboobie.homelinux.net, so I configured my zimbra test box as crobuzon.kaboobie.homelinux.net. My ISP won't let me make outgoing port 25 connections, so I un-checked 'Enable DNS lookups' and set the 'Relay MTA for external delivery' to my ISP's (smtp.east.cox.net.)

    This worked well, and I was able to send mail.

    I then used imapsync to copy all of my mail over from old server to new zimbra server. That went well also, so I decided to de-commission my old server and replace it with my new zimbra server.

    I brought my old mail down, switched the IP of my zimbra server, changed /etc/hosts on the zimbra server to reflect the IP change, renamed the 'Service Host Name' of my server from crobuzon.kaboobie.homelinux.net to kaboobie.homelinux.net. Created a new kaboobie.homelinux.net domain. Moved all of my new users to the kaboobie.homelinux.net domain. I have a local DNS server, so I made the appropriate changes there also.

    Everything works, except sending outgoing mail. I _always_ get a connection timeout when trying to relay through my ISP's mail server now.

    I can telnet to port 25 on my ISP's mail server and send email, so the problem isn't there.

    I presume the problem somehow has to do with my attempted rename of the domain, or some such zimbra internal hostname setting. I note that, while the 'Service Host Name' of my server is now kaboobie.homelinux.net, the 'Display Name' is still crobuzon.kaboobie.homelinux.net.

    Here's some log showing the connection timeouts.

    Any idea why changing the hostname (etc.) would cause this problem and how to fix it?
