Hi
For those who operate public facing SMTPd that receive a large volume of incoming traffic, and accordingly, a lot of spam...
How much weight do you put on an incoming message, in terms of adding additional score towards a possible value of spam, for total absence of DKIM signature?
No DKIM = not scored. DKIM is not widely used and DKIM does break a lot of mailinglists and sometimes also SRS compliant forwarding. We do score some points if a DKIM header with invalid signature is present. -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
