Anti-Spam Feedback

To improve the spam filters we need a feedback by the users.
False positives are legitimate e-mail messages that are mistakenly blocked or tagged as spam by the anti-spam filter .
On the other hand there are e-mails (false negatives) that pass the anti-spam filters and arrives on the users' inbox, but they are spam.

Our internal anti-spam Barracuda Spam Firewall assigns to every incoming mail a spam score value. E-mails with values higher than 3.5 are probably SPAM messages and the anti-spam tags their subject line with the identifier [Maybe SPAM]

Only the e-mails with very-very-high spam score (spam score over 9 points) are blocked by the Barracuda Spam Firewall.
The others –allowed or tagged as probably spam– are delivered to the final user.

When you find a:

• false positive –mail tagged as SPAM or “[Maybe-SPAM]”– which is NOT a real spam

or

• a spam mail without “[Maybe-SPAM]” in the subject,

please forward it, with its complete header, to spam@sissa.it specifying in the subject if it is:
a FALSE POSITIVE or a SPAM.

The operators take the notifications and update the filters.

The COMPLETE headers are needed because they contain the information about the real sender and the e-mail delivery. We will take the notifications and update the filters, in order to make the filtering better.
You find here a typical header example.
You find below some instructions to correctly send us the complete header.

You must enter/exit the header mode with the key H. When you enter the header mode The program shows at the bottom of the screen the [Display of full headers is now off.] or [Display of full headers is now on.] Now you can forward us your e-mail.

Open the message and then select the menu View –> Headers –> All: you will see on the message window the complete headers of the messages. Now you can forward us your e-mail.
