Mail with no From

Hi,
I noticed a problem on my EFA server that I use for more than one month. Some emails with a empty "from" are considered spam and others not.
When I check on the web control panel of EFA server the information in the mail to see witch rules increase the spamassassin score, there is nothing registered, only the high score is showed.

When I check what are this mails, often it's a confirmation that the email was successfully delivered, a problem with sending email (mailbox doesn't exist) or an automatic response (vacancy). So, maybe 90% of time, this mails is nonspam and need to be delivered to my users!

So how can I know witch rules affect this score (for tweaking it!)?

I attached some screen shots to explain what I see!

Thanks for your help!

Jeff

And this is my current config in MailScanner.conf

Check Watermarks With No Sender = yes
Treat Invalid Watermarks With No Sender as Spam = 2

I just change one settings:

Check Watermarks To Skip Spam Checks = no

Before this settings was set to yes, I I only have one mailscanner (this one), so maybe this option will correct my problem!
