Strange mail looping issue
There is a strange mail looping issue on one of our mail clusters. I believe I have the problem nailed down, however I haved turned off postfix on our inbound MX servers. This will only affect a limited number of customers. No email is lost, and it is only looping for a single mailbox of a single customer, but it’s causing mail queues that are growing at a rate of hundreds per second. All email should be flowing inbound again in about 15 minutes.
