does the "too many hops" error mean when an email message I send fails? When you send an email message over a network, it is transferred to smtp 554 5.4 6 too many hops and through several computers before it gets to its destination.

to correct a "too many hops" mail return. If you think a mail forwarding loop is causing the error, you can contact the person with the loop through a method other than the email address causing the error. If you know a mail forwarding loop is not causing the error, ask your system administrator to increase the maximum number of hops allowed. Mail forwarding too many hops 26 (25 max) loops A mail forwarding loop can occur when you set up mail forwarding on two accounts so that the first account forwards all its mail to the second, and the second account forwards mail back to the first. If your mail delivery system had no limit on hops, your message could be bounced back and forth between these two accounts indefinitely. Frequently, when a message you sent returns to you with the "too many hops" error message, it means the recipient has set up a mail forwarding loop. Distribution lists If you are an owner of a distribution list and your list gets the "too many hops" error message, you may have more difficulty identifying the sender because the error message typically does not include the exact email address(es) causing the problem.

I tracked down the error to the postfix mydestination config (/etc/postfix/main.cf). For some reason the line had been commented out and replaced with mydestination = localhost #mydestination = mymailserver.com, localhost.com, , localhost mydestination = localhost I fixed it by changing https://github.com/mail-in-a-box/mailinabox/issues/713 it to: mydestination = $myhostname, localhost.$mydomain, localhost I have no idea if/why it changed and I only just started getting reports of the undeliverable mail from a user today. Maybe this will help someone else. Mail-in-a-Box member JoshData commented Feb 15, 2016 The original is correct. There must be something else on your system that is different/incorrect. pryley commented Feb 15, 2016 Ok well since you said it was correct, I've changed the postfix setting back to mydestination = localhost.

Is the NDR generated server remote server or self Exchange server? If it's internal recipeints, you can use Message Tracking Log to find the possible cause. It it's Internet recipients and the remote server generates the NDR, that should be the destination server issue.
