Re: Incoming Email Problems (550 5.7.1. relaying denied)



Actually, "pigeon" is our mailserver. "Queue" is, I believe, our ISP
mailserver. Why would our mailserver be unavailable? Some SMTP mail
is coming in, some isnt. I know its not COMPLETELY unavailable... Any
ideas on where I should start looking for the problem?

You have got two Mail eXchangers for your domains:
Non-authoritative answer:
swu.edu MX preference = 10, mail exchanger = pigeon.swu.edu
swu.edu MX preference = 20, mail exchanger = queue.newsouth.net
none of which appears to be Exchange. "pigeon" appears to be some kind
of firewall, "queue" looks like ISP mail server. What could be happening
is that when "pigeon" is unavailable for whatever reason, sending
server attempts "queue" which rejects the message (because it is not
setup to accept mail for swu.edu). It really rejects it - I just tried that.

Good morning,

I'm having problems with incoming email to my network. Mail coming to
my exchange 2003 server seems to get stopped somewhere, but I'm having
trouble tracking it down.

I discovered the problem when users on my network were being removed
from mailing lists due to undeliverables. I recently found out that
they are later getting notifications of this saying "550 5.7.1.
<user@xxxxxxxxxxxxx>...Relaying Denied."

Its not ALL incoming email thats getting stopped, but mostly
newsletters, etc. I've also noticed I'm not getting my online bank
statements due to undeliverable errors they are recieving.

Can anyone help with this? If you need more information, I'd be glad
to provide it. Just let me know what you need to know.
