External Domain Emails Caught in Quarantine
Problem reported by Adam Lewis - November 3, 2016 at 5:29 AM
Not A Problem
Here's the setup:
 
DomainA is setup with a Domain Location of External (user host address) because they want to use our spam filtering.
 
Whenever DomainA receives an email from example.com it goes into our Spam Quarantine. Here is a link to all the relative settings for our spam filtering - https://www.dropbox.com/sh/btjcp0ohb2isaek/AADfiWofwrF19aV3WpsKN-3-a?dl=0

We have added the IP address example.com's email to our Whitelist and SMTP Authentication Bypass
 
We've added the domain to our Trusted Senders.
 
Still, every example.com email gets marked moved to Quarantine.

Adam,
 
Based on the logs, its getting flagged from Cyren. This may be a false positive that's matching a certain holding pattern, I would suggest sending an e-mail to sales@smartertools.com and attach the e-mail in question. We can request that this is de-listed, usually these requests take 15-20 minutes to process on Cyrens end so we should see a fairly good turnaround on this. 
 
We will spam check outbound messages to the external domain to prevent blacklisting on major providers such as Gmail\Google apps for example. If the domain was hosted with google apps and was knowingly sending spam out to the Goole Apps domain and the google apps members were marking these as spam, the SmarterMail servers IP reputation will take a hit with their services. 
 
I hope this helps clarify.

Von-Austin,
 
I did what you said, and Rose responded with the following:

"The Result of the reported FP (RefID: 0001.0A020201.581BC149.001C): Not blocked. The message was not classified as spam/bulk. It is possible that the message was classified as "suspected" by Commtouch or blocked by another engine; it is also possible that there was a reporting error.
 
I realize this isn't the answer you were expecting.  But I hope that it points you in the right direction for investigating.  Please let me know if you have any additional questions.  I would be happy to assist."

Any more ideas?

Adam,
 
It could be that the holding pattern has already been released. If you perform a test with the same message, does it get blocked ?

This customer is already pretty pissed off, so I don't want to use the same email to test or they will get another copy of it and yell about that I'm sure.
 
I just had 3 more emails within the last hour from example.com get moved to quarantine.

At this point, I'd suggest opening a support ticket with us so we can investigate your logs and see what may be tripping these up.

OK so there's this:

*************************************************************************************************************************
 
It clearly passes all the checks listed, yet it is still flagged for quarantine. The question remains: was it flagged for quarantine BEFORE all those checks, and if so, why is this not able to be noted in the log? If it was only flagged AFTER those checks, then something is amiss in the logging/reporting process as well.
 
I now see that the last reply is several days old. I am curious to know what the resolution was, if any, to this issue. Thanks!

Oops!  Now I see that. I stand corrected!
 
My apologies.  Would still like to know how this was resolved, however,
 
Cheers.
