DSPAM提示“Unable to find a valid signature. Aborting.”错误信息!

以下是我的配置:
vi /../postfix/master.cf
spam unix – n n – 10 pipe
flags=Ru user=dspam argv=/usr/local/bin/dspam –class=spam –source=error –user mydspam
ham unix – n n – 10 pipe
flags=Ru user=dspam argv=/usr/local/bin/dspam –class=innocent –source=error –user mydspam
vi /../postfix/transport
[email protected] spam
[email protected] ham
vi /../postfix/main.cf
dspam_destination_recipient_limit = 1
dspam-add_destination_recipient_limit = 1
dspam-fp_destination_recipient_limit = 1
local_recipient_maps = $transport_maps
#end

请修改:
spam unix – n n – 10 pipe
flags=Ru user=vmail argv=/usr/local/bin/dspam –class=spam –mode=teft –source=corpus –feature=noise –user mydspam
ham unix – n n – 10 pipe
flags=Ru user=vmail argv=/usr/local/bin/dspam –class=innocent –mode=teft –source=corpus –feature=noise –user mydspam
