Dear Kerio-Community,
we run the most recent version of KC 9.2.2, no spam assassin activated (yet), bitdefender Anti Spam active, company network whitelisted, spam filtering configuration "process messages from trusted sources (SMTP / relay options) active - and I will not change that setting.

Problem is: Every now and then a mail from within our network will is being considered "phishing spam". I need to analyze why.
It is always a Mail containing a zipped PDF file - which - being a prepress department - is daily business of course.
I can reproduce that behaviour but not really identify the reason.
I can send a zipped or unzipped PDF file with a few numbers and a colored area to a colleague and it gets filtered. I can send a different PDF zipped or unzipped and all is fine.
How does that phishing spam filter work?

Thanks a bunch and all the best from Germany
