Email invoice Rejected

Hi Jemar_C,

We are facing same issue in our business associated to our email. Could you please contact me privately so I can share our email to be released from the blacklist? It is quite urgent. Thanks

Hi epineto,

Welcome to the Community Forum!

I understand the urgency of the situation and would be happy to help. I've sent you a private message so we can discuss the details and work on getting your email released from the blacklist. 

Cheers,

HI Guys we are having some rejection problems too - we can receive and send emails using Outlook but MYOB sent emails says rejected.  How can we sort this?

Hey Trushka,

It looks like the rejection email might be due to the recipient's email address being blacklisted. I'll send you a private message to grab the email address so our team can check it out. If it's on the blacklist, we'll get it sorted, and you'll be able to resend the invoice once everything's cleared up.

Cheers,

Doreen

Hi

I have 3 emails from different hosts/providers - so I tested sending invoices and statements to myself.  One of the three addresses did not receive anything despite MYOB Sent Emails saying it was all good.  That host had a look, fixed it and said: 

"There’s something about the MYOB email format that some spam filters don’t like so quarantines them by default.

I’ve had to put an exception rule in to explicitly exclude them from mail filters."

If any of your customers say they aren't receiving your emails this might be the problem.

Hi Doreen_P 

I am also having this same issue - it commenced from 1/11/2025 and is driving me crazy!  I have two email address that are have the same domain name but a different beginning that this is happening to.  Are you able to assist me as well please?  Thank you!

Amy.

Hey BWBServices,

I hear you— dealing with this can be frustrating. I'll send you a private message shortly to assist. Just reply with affected email addresses so we can check if they're blacklisted.

Cheers,

Hi, 

When sending invoices to my regular I'm receiving this back

Sorry, email delivery was unsuccessful.

Diagnostic-Code: rejected

How can I fix this issue?

Thanks 

Chris

Hi Chris_Ch, 

Sounds like the emails are being rejected by the receiver's end. That “Diagnostic‑Code: rejected” message is coming from your customer’s email system; it’s their mail server knocking the invoice back, not MYOB refusing to send it.

Ask them to check their Spam/Junk folder and to add the MYOB address the invoice comes from (usually noreply@apps.myob.com) to their safe senders list, or get their IT/help desk to do that. That basically tells their system, “emails from MYOB are okay, don’t block them”.

There’s a short rundown on this error here if they want more detail:

If you want us to check our side for any block on their address, flick us a Private Message with your serial number and the exact email address that’s bouncing, and we can take a look.
