Czesz Vlk,
You can give Mailwasher some eyes. Go inside Mailwasher to Options, then General and Edit DNS Blacklist servers, click and edit it and save. I check my mails on my ISP popserver against several spam list servers, like SpamCop, ORDB, Deadbeef, Spamhaus, Five-ten, Abuseat. Well that is just my personal collection to check against, works beautifully, nearly none missed.
All these mails are flagged accordingly (blacklisted in red letters), and are deleted in one go manually by me or those falsely flagged reset on the ISP mailserver and these I want land in my Inbox. Spam is deleted and blacklisted, but never bounced. It is working perfectly for me, great solution from the developer "dunder from down under". Mailwasher is my "pralka e-mailowa".
pozdrawiam,
