Undeliverable Emails

Question

Getting a whole bunch of bouceback emails from bounce@apps.myob.com
All emails contain the same error "Diagnostic-Code: smtp; 550 5.7.1 Policy-DT510: Rejected content policy violation

Some of the emails were sent to:
@optusnet.com.au
@Froggy.com.au

All started the day after I sent out my monthly invoicing.

Thank you for your reply.

I have already tried adding all the MYOB domains in the customers whitelist but that wont help as the MYOB emails are being blocked at a server level so the email wont be received by the user in order for the whitelist to come into effect.
I have just spoken to someone who uses AccountRight and they too were unable to email an optusnet.com.au customer. Surely we cant be the only 2 who have been affected?

Hi @VT3,

Good catch on the timing, looks like things started going sideways the day after. No worries, we'll sort it out. The “550 5.7.1 Policy‑DT510” error could mean two things, either the recipient’s mail system is blocking/rejecting the email (ask them to whitelist MYOB’s email-sending domains), or the address might be blacklisted on our side. You can reach our team on live chat via our virtual assistant MOCA or raise a support ticket in My Account. Share all the bounce-back email addresses and we’ll check each one for blacklisting.

Cheers,

Princess
