#5.4.6

[daztrouk]

I have an issue. I can receive from an email address, but no one can send emails to it. When an email is sent to the address, we get a bounce-back that states:


Your message did not reach some or all of the intended recipients.

Subject: RE: test
Sent: 21/02/2008 12:41 PM

The following recipient(s) could not be reached:

X on 21/02/2008 12:41 PM
A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.
<X.X.co.uk #5.4.6>

I've been searching all morning for a fix, but havn't found one, any ideas on how to fix this?

where are you sending the email to?


if you break down the error message given by external mail server according to RFCs you get:

5.x.x - permanent error

X.4.6 - Routing loop detected

A routing loop caused the message to be forwarded too many times, either because of incorrect routing tables or a user forwarding loop. This is useful only as a persistent transient error.

It looks like the relay for the target mailing domain is misconfigured

managed to get it sorted in the end. mailbox 'a' was forwarding its mail to mailbox 'b', and mailbox 'b' was forwarding its mail to mailbox 'a'. Nice and simple. Cheers for the help
