I'm seeing some emails not coming through. They are being rejected, though the sender is in our whitelist. I "think" this might be a Bitdefender issue, but I'm not entirely sure. The email being rejected has some flight booking info in a pdf. If I have the recipient use a personal account, they get the email with attachments. If they then try to forward it to his domain email account, it's rejected. So, it's not the sender that is being blocked, but the attachments must be causing the issue.
How do I get around this? I can't have false positives rejecting email that is critical to what the company does. Any ideas on how to solve?

It's not clear to me if it's being dropped as 'spam' or 'malware'.
I have Antivirus > 'Deliver the message with malicious code removed' selected. I would have though the user would get the message, but the message is just dropped.
I currently 5 to Spam Score for Bitdefender. I will change that to 4.

lately we have tons of internal email traffic marked as malware or phishing. Even really simple emails.
As we have another Spam/Phishing filter in front of Kerio, we disabled the Malware/Phishing filter in the mailserver.cfg but kept the rest on.

We had to do this too...too many false positives lately.

This has become a Whack-a-Mole situation. I keep getting valid emails coming from our vendors and customers with .pdf attachments that for some reason or another Bitdefender spits back with a malware or Spam judgement and then I have to whitelist that domain so that I am not babysitting the Kerio quarantine. Turning it off as some have done seems to be the poorer choice if the product is a paid for add-on to Kerio Connect. It should work as expected time and time again. Is it something to do with the variety of creators for .pdf documents and that Bitdefender only knows something about a few so those pass through as clean? Just guessing, but at the least we should be informed as to why we have to submit case after case to support and they adjust for that one situation only. Maybe Bitdefender is just not a good product to be using? We also have Sophos Email Security running as a pre-filter and it sees no issues with these documents. Its frustrating.
