Good afternoon, I have a bit of brain freeze I could use a jab in the right direction with.
If Exim tries to deliver a message to a remote server and gets a 5xx code back, say 550 no such user, am I right in thinking the message should fail right away with an NDR, not remain on the queue being re-tried? More sticky, if a remote server refuses connections from Exim - say it is firewalling off the connecting ip, should that fail at once or stay on the queue for x hours? I'm sure in the first case it should fail at once, and in the second retry as the connection error could be transient, but I'd like to know for sure before I start troubleshooting.
