Good afternoon,

I have a client who's emails started getting blocked on March 1st to a specific email. I have tried emailing  investigation@review.symantec.com, but it bounces back with this responce:

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

<investigation@review.symantec.com>: 554 5.1.2 Recipient address rejected: User unknown

I have tried emailing CLOUDfeedback@feedback-87.brightmail.com with not responce or a notification of it being delivered. I have called the support 1-800 number and was directed to the sites I have already been to.  If there any way to get a domain or ip address removed from the blacklist that actually works?

Any help would be appriciated.

Thank you,

Tyler

I was just told by support to send evidence to "investigation@review.symantec.com"

Remote Server returned '554 5.1.2 < #5.1.2 smtp; 554 5.1.2 Recipient address rejected: User unknown>'

We were a previous customer and they won't assist us now that we are no longer on their platform.  It looks like when they decommisioned our account they left the static routes in place.

So frustrating.
