Exchange Transport Content Filering False Positive

Hi everybody

The following mail considered as spam (flase positive) by Exchange Edge server 2013 and moved to spam quarantine mailbox specified in the contentfilter config. While analyzing the header I didn't see any thing wrong with the sender. Any ideas?Thanks in advance

Hi Noufal,

As the suggestion above, you can use to troubleshoot if the issue is associated with Content Filter agent.

In addition, you can also try to bypass this sender or his domain with the following command and check if any helps:

Set-ContentFilterConfig -BypassedSender  e-ooredoo@ooredoo.qa

Set-ContentFilterConfig -BypassedSenderDomains ooredoo.qa

Did you try sending this email to your personal account hotmail, gmail  and see if where this email gets landed ?

This is important incoming mail from  third party , like billing statement from Wowza (http://www.wowza.com) . When I forward by clicking "send again" from quarantine mailbox it goes to inbox of the recipient.
