Mail delivery failed: returning message to sender

Hello,

 

I need some assistance to prevent this from happening again!

 

I configured QBs to send out emailed invoices and statements today.

Sent out 1 test email and 5 invoices to the same client/email address - 6x emails...
All emails BCC to gmail address for records...

1 of the 5 invoice emails did not go through and was blocked for both the client & gmail address...

Mail delivery failed: returning message to sender
[email address removed]
host smtp.ucebox.co.za [xx.xx.xxx.x]
SMTP error from remote mail server after end of data:
550 High probability of spam

 

Thanks,
