In advance?

You can't.

 

If signature is part of message body, any url should be analyzed too.

If your senders are trusted, you could whitelist their signature urls.

Can you DM me a sample of the Sig URLs which are triggering?

It's not easy, it's a lot different because we work with many companies and doctors. Most of the links are on their homepage and on their Facebook page.

I think i have to go another way...

Then I am surprised that they are triggering the block, unless you have the FML to quarantine on unrated.    Can you share the relevant logs?

What kind of Logs exact do u need?

in eatch html signatures are jpg or png, this is also a reason to quarantine for the FortiMail... i see in the Log that each picture is scaned by antivirus with result "clean" but on next step there is an rult to quarantine images/jpg and images/png

Make that sense when the FM scaned with result clean?

Find a few examples where there is a block in the History Log, right mouse click the log and Cross Search (Message) > 10 Minutes then download the resulting logs.
