Hello,
I receive on a regular basis (several a day) blank messages that are obviously spam, here two of them as examples (below):
Return-Path: <Franklin_Sabrina30@corexsud.com> X-Original-To: jdd@dodin.org Delivered-To: jdd@dodin.org Received: from 94-183-247-79.shatel.ir (unknown [94.183.247.79]) by ks311900.kimsufi.com (Postfix) with SMTP id B2554C0234 for <jdd@dodin.org>; Wed, 6 May 2015 01:33:06 +0200 (CEST) Message-ID: <8[10

as you can see the return path and the from are different for each message.
Thunderbird anti spam do not see them. I fear filtering out all blank message may me miss some friends error.
the kimsufi part is my own imap server
what do you think?
I think greylisting would probably solve the problem. Alternatively, you could ignore blank messages from servers with poor reverse mapping (both of them above). -- Per Jessen, Zürich (11.8°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
