  • 1.  Email not received by Message Labs customers, no NDR

    Posted Aug 02, 2017 06:56 AM

    Hi,

    One of my customers is having trouble emailing a supplier who's email is being filtered by MessageLabs.

    The sender receives no NDR but the receipent never receives the email.

    I've done a blocklist lookup on the senders IP address 82.70.102.70 and they are not listed anywhere.

    Please advise how we can get to the bottom of this issue?

    Hi

    I checked your IP address and can see no issue with this anywhere, As such it is most likely that there is a rule in place which has identified your mails as spam. As such please follow the process laid out here: https://support.symantec.com/en_US/article.TECH82881.html

    Thank you
