I changed it to one of our unused real-world IP address, and made a
firewall rule to reject all packets destine for that IP.
This seems to have the desired effect and I dont think there are any
security issues.

I am using a black list from here:

I'll have to remember this next time I have weird mail issues.
Your mail server should use a reliable, honest DNS

Your mail server should use a reliable, honest DNS server.

It was my DNS.

Problem solved
Thanks for all the help

Correct.

host -t mx juno.com
juno.com mail is handled by 10 mx.vgs.untd.com.
juno.com mail is handled by 10 mx.dca.untd.com.

Who said "juno.com" is the reason it is delivered lo
I commented it out and tried again, it didnt make a difference.
I cant think of any reason this server would think it should deliver
messages destine for juno.com locally.

Where the Postfix SMTP client should deliver mail when it
detects a "mail loops back to myself" error condition. This
happens when the local MTA is the best SMTP mail exchanger for a
destination not listed in $mydestinatio

I sent this message you see in the logs, it was a test message.
If I send to [EMAIL PROTECTED] I will receive it local, because this is a
user local to this server. It should not be accepting this message, it
should send it on to the real juno.com (which probably doesnt have a
nobleja user AFAIK)
