Hello,
Spamgourmet send me messages with from addres @ob.0sg.net
Goole says :
Received-SPF: none (google.com: gourmet8.spamgourmet.com does not designate permitted sender hosts) client-ip=216.75.62.102;
Authentication-Results: mx.google.com;
spf=neutral (google.com: gourmet8.spamgourmet.com does not designate permitted sender hosts) smtp.mail=;
dkim=fail header.i=@ldlc.com
and effectively there is no spf record :
; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> @localhost ob.0sg.net TXT
; (1 server found)
;; global options: +cmd

if the from addres would be only @0sg.net spf would be ok.
