I recently asked support the following question and received the following answer:
Q: How do I Manage Spammers with subject lines, NOT email address or domain?
A: Unfortunately, with the Bitdefender Antispam module, you can only Manage Spammers by email address and domain name.
This is a VERY BAD PRODUCT DESIGN!
Example: you bank with Bank of America. You certainly want to receive your emailed statements, info about your accounts, etc. But you do NOT want to receive their constant spam about Auto Loans, Home Improvement Loans, etc. By not allowing classification of spam on subject keywords (I.e., "auto loans" "home improvement loans" etc, you are FORCED TO ACCEPT THEIR SPAM.
BitDefender - your product designer(s) are not innovative and in fact, very unintuitive about how the real world works. You need some new ones.
