Getting email returned from the Mailer-Daemon

Posted on 2002-05-09
Last Modified: 2010-03-05
We recieved a message back from our isp saying "Sender domain not compliant with RFC 822, section 6.2.7"  Sorry, guys, went to tech net first and couldn't find anything.  If ya'll answer this one, I'll always come here first!
It also says "this message is in MIME format.  Since your mail reader does not understand this format, some or all of this message may not be legible."

Just a single message?  Can you post the entire content of the return message?

I thought so.  Mindspring has been known to pop this error from their servers.  I assume that you have only gotten a few of these?

This is the first I've seen from mind spring.  Is there nothing I can do?  Here is another one, but a different problem.

No action is required on your part. Delivery attempts will continue for

remains undelivered. Eventually the mail delivery software will give up,
and when that happens, the message will be returned to you.

There is not much you can do about the RFC related error.

The other error is unrelated.  The remote mail server may not be responsing.  Most mail relays will only attempt to deliver for 24 hours.  After that they report NDR.  

The MX record for this domain(
 is a little off, it could be causing delivery problems.
