Two days ago I changed ISP. This means that my public IP changed, but nothing internal to my network has changed. I have updated DNS registration and reverse DNS (tryx.org, and 18.104.22.168, respectively) I have rebooted my Zimbra server.
Incoming mail was restored as soon as my DNS updates had percolated through the net. As of this morning, I have incoming mail with no problem, as nearly as I can tell, but outgoing mail is failing with the message in Zimbra.log, "Connection timed out". Any thoughts?
Thanks for the help,
