Hello Jack,

We recently migrated technicaldiagnostic.com from Exchange 2010 to Exchange Online via Hybrid Configuration Wizard. We now are unable to send email to a few select people. We are not blacklisted/blocked. Domains are: jpsco.com, valero.com, lkcm.com

I assume that we will encounter more blocked domains. Please advise how to fix. We've exhausted thetroubshooting options.

Hello

Still have the same problems.

Is anyone here?

The recipient's spam filter was blocking because I was running in hybrid mode and my spf record only pointed to outlook.protection and not my public IP on the on-premise Exc10 server. I added the IP to the spf record and it worked fine.

Email from our domain (firstannapolis.com) sent via our Office365 email service through Mimecast to several of our clients is being blocked, with the following error:

Remote server returned an error -> 553 Message filtered. Refer to the Troubleshooting page at;http://www.symanteccloud.com/troubleshooting for more;information. (#5.7.1)

I have followed the steps on the troubleshooting guide and I have also forwarded several attached messages to CLOUDfeedback@feedback-87.brightmail.com.

Please advise on how we can get the block lifted.  This has happened twice in a two week period, and we have no issues with blacklisting or our SPF record.

Thank you in advance for your  help.

Hi,

I sent many emails to cloudfeedback@feedback-87.brightmail.com.

However I did not have any answers and still continue with the problem.

I'm having serious problems with my client ;-(

Can you help me with this?

This is happening with a number of email addresses from our domain.  Sent by private message.

Thanks for looking into this.
