Would be good to see the anti-spam settings expanded to include the option to modify the email header with an appropriate Kaspersky entry.

I am particulary thinking of Thunderbird users who do not have the ability to modify a received message's 'Subject' line (like you can in MS Outlook) and may wish to remove the 'SPAM' addition after the message has been received and filtered.

hello
so instead of changing the subject to spam, just add something in the header? yes, that would be a nice idea if it wouldn't break anything. i also think there's an addon for TB which can modify subjects.
