Receive mail error - 550 Relay is not allowed, why?
This is using MS Exchange server 2016. Recently, a user tried to send an email to a business partner, and received the bounced mail as follows,
sgsmtp4.sgcloudhosting.com rejected your message to the following email addresses:
jabc@arxcent88.com (jabc@arxcent88.com)
Your message couldn't be delivered and there was no valid enhanced status code being issued by the remote mail system to determine the exact cause, status: '550 Relay is not allowed'.
sgsmtp4.sgcloudhosting.com gave this error:
<jabc@arxcent88.com> Relay is not allowed
To verify, I also sent an email to the above recipient and ended with receiving the same bounced mail with same errors. This looks like is the above receiving mail server is having problem.
What can we do in order to be able to send email to the recipient without receiving bounced mail?
Thanks,
ASKER
Yes, I anonymize the email address.
Understood.
Suggestion: Open a new question describing what problem you're trying to solve by anonymizing your address, then ask how others have solved this problem.
There are usually fairly simple MTA config fixes to solve most reasons... at least that I can think of right now...
It's not your responsibility to solve this (nor can you if you wished).Get the other side on the phone (or any other method except email), get them to contact their IT dept/mail server admin, to fix it. Tell them your error message, tell them you will receive it always (including testing from gmail/hotmail, therefore proving it's not an error on your side).
Edit: did you anonymize the email address btw? the current email address in your post, does not exist at all. If you made a typo, fix it. If it's anonymized, my above reply is still valid.
