The following is an excerpt from a failure message that I received as administrator of a mailing list:

64.202.166.12 does not like recipient.
Remote host said: 553 sorry, relaying denied from your location [69.5.6.150] (#5.7.1)
Giving up on 64.202.166.12.

--- Below this line is a copy of the message.

Here are some details that may help: a message was sent from a frontiernet.net user to my FQ mailing list: csh1@lists.cfidsselfhelp.org. Based on the message from the remote host (553 sorry, relaying denied from your location [69.5.6.150]), (an FQ IP address) I came to the conclusion that the recipient host doesn't like the FQ IP address. And yet I've never seen all this 'relay' stuff, and the relay seems to have occured inside of frontiernet. So I'm all confused. I've been in contact with both the sender and the receiver and they both want to send & receive messages to this mailing list. I'm thinking that one of their hosts has a problem with our IP address, but I'm not sure which one. Both users have been actively using the mailing list over the last 6 weeks, and this just came up for the first time today, so I guess a new policy has been implemented someplace.

My users are dazed, confused, and frustrated. If I can figure out more clearly what this message means, maybe I can help them resolve the issue with the appropriate host.

Thanks for any help! - Jan

The information that you have posted indicates the error message is coming from the recipient's server. For what it's worth, I've seen misconfigured servers that issue messages that do not appear to make sense given the circumstances (such as stating that a remote address delivering to a local one requires authentication ... which is what the "no relaying" message you posted typically means).

If you feel there is more to it than that, then you will need to send the complete bounce message, including the recipient's email address, to the Service Desk and we can search the mail logs to see what happened when our server tried to deliver it to the remote network.

Without the recipient's email address, it is not possible for us to search the mail logs. But you will not want to post it here in the forums, so send all of the details regarding this situation, including the full bounce message pasted into an email (not as an attachment) to Service@FutureQuest.net .

Thanks, Sheila, I'll do that. - Jan
