The issue looks like its one involving the SMTP setup of the client that the mail is sending from.

SeoDorks

I just tried sending emails through Webmail though?

Ryan Woods

And that too is rejected? Internal relay access denials generally refer to misconfigured SMTP settings or MX records.

SeoDorks

Correct.

Ryan Woods

hmmm try this for me...

Send a test message to support at thexyz.com from the affected mailbox.

Ryan Woods

Just checking in. I don't look to have received a message yet.

SeoDorks

sent \

Ryan Woods

Okay outside of the initial failures you posted above there were some successful tests on the recipient domain, is that right?

SeoDorks

yes

Ryan Woods

To verify, the failures that were sent were sent from Webmail ?
