Hello, recently I have introduced to postfix the mime_header_check with the rule to bounce messages including attachments with executable files based on a suggestion in this list. I have tested that and it seemed to work fine. Nevertheless since Sunday I am receiving (and other users of the server, too) many mails containing the w32.swen.A. It's strange, as this mail contains a file xxxx.exe attached. Is there a way to modify the postfix conffiguration to stop these (and may be similar mails in the future) mails? Seems that this type of attachment bypasses somehow this filtre. I have checked the message, and did not find a difference with otrher types of attachments. Thanks in advance S pozdravem Vaclav Brunnhofer =============================================================== | Entomologicky ustav e-mail: vbru@entu.cas.cz | | Akademie Ved Ceske Republiky tel.: 038 7775251 | | Branisovska 31 fax: 038 5310354 | | 370 05 Ceske Budejovice mobil: +420 606 632822 | ==============================================================
