Our domain and email server can send and
receive emails from only within our domain.
We can send emails
to external email services successfully.
We can in instances receive emails sent back to
our domain by way of reply from external internet email
services.
In pretty much every
instance, when someone from outside our domain sends an email to anyone in our domain, it bounces back
with an error that the email was rejected due to a "mail loop state 14".(from Gmail) or, address generates mail loop [RCPT_TO] (from Yahoo).
I've checked my MXToolbox for blacklists. None found. I've run dns reports from dnscolos.com. These reports fail the Mail server connection test
HELO, MAIL FROM, RCPT TO, QUIT with this information:
Connect to mailserver mx00.1and1.com FAILED (could be greylisting)
Connect to mailserver mx01.1and1.com FAILED (could be greylisting)
1and1 is our host site but our mail server is local. The dns check from 1and 1 shows the MX record of exchange.odysseycharter.org, 10...as it should be.
If you can offer any help, or a thread to pull on, it would greatly, greatly be appreciated.
