previous settings were reasonable for a well trained dspam. After starting with a fresh dspam, the settings were not optimal for the amount of naive that a default dspam is.
process_backticks now writes the entire message (headers + body) to a temp file and had dspam read that. Previously, dspam only read the body. With the new "process, then train on error" method, dspam didn't have access to the DSPAM signature (in the headers).
replaced open2 with open3. Same results. Works part of the time, but not consistent, and I haven't been able to figure out why.
dspam transaction note is now a hashref (was a string)
parsing of dspam response via substring (was regexp)
expanded POD
cleaned up stray EOL spaces
added lots of logging, with standardized [ pass | fail | skip ] prefixes
added reject_type option
use split for parsing dspam headers
use SA note instead of parsing headers
added reject = agree option
store & fetch dspam results in a note
