I recently upgraded my mail server and moved over to rspamd for spam management. What I didn't notice right away is that the upgrade mail server is sending temporary error 451 messages to the xenforo server. It looks like its mostly doing this since xenforo is sending a smtp helo with the ip of 127.0.0.1 even though its on a different server (connection over IPv6 if that matters). So I have two questions, first is there a way to change the helo name/ip that xenforo uses when it communicates to a mail server and does Xenforo try to resend those messages at a certain point when it encounters a temporary error? Not sure if it does any queuing or not. Thanks
