I just upgraded to 18.104.22.168 and everything looks good but I have one problem. I configured the server to relay mail through my mailserver instead of the ISPConfig Server (this has been working flawlessly for over a couple of years). After the update, mail is no longer being relayed to the mail server on the LAN. I have issued the "mail [email protected]" and mail does not send. I have mail forms which were sending but they are no long sending as well. I have noticed that the new ISPConfig comes with a DNS server and Mailserver services to disable and enable. I think something has broken my internal mail relaying and I am not sure what the problem is. I have read the postfix docs, looked at help pages and reconfigured for mail relay (which always worked) but to no avail. The ISPConfig Web UI shows the following in the logs: /usr/lib/postfix/trivial-rewrite: bad command startup -- throttling Can someone help me please?
