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 and through several computers before it gets smtp 554 5.4 6 too many hops to its destination. Each transfer between computers is called a hop. The "too many hops" error message means too many hops outlook there are too many transfers between you and your recipient. To prevent mail forwarding loops, most mail delivery systems limit the number of hops they will process before stopping

a delivery attempt. There is little you can do 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 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.

Works perfectly for incoming and outgoing mail to other domains but fails when trying to send mail to a local user. Here are my settings:example.com is my primary domain, it provides DNS and Mail servicethere are other domains being hosted (web) with example.com providing mail service for them.Mail Server setting under "Provide Mails for...": Domain Name is example.com, Virtual domains: myotherdomain.com, example.com (included in list, is this correct?), and some moreDNS settings: each domain has a machine record for the domain name (e.g. example.com has an A record, myotherdomain.com has its own A record), each domain has an MX pointing to example.com. Domain example.com has an alias (CNAME) record mail.example.com pointing to example.com. This is the only place where the name mail.example.com appears in the whole server.Last night I tried to reply to a mail I received from a user on myotherdomain.com. My receiving account is also on myotherdomain.com (myotherdomain.com is one of my domains with MX pointing to example.com). When I simply hit reply the mail server eventually reported back that the mail was not delivered due to too many hops.Here are the headers from the mail I received. I simply hit reply and got the too many hops. WHY? Return-Path: Too Many Hops (in Reply To End Of Data Command)
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 it to: mydestination = $myhostname, localhost.$mydomain, localhost I have https://github.com/mail-in-a-box/mailinabox/issues/713 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. So the original problem was this: This is the mail system at host spam.flamble.it. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
