Integrating with Communigate Pro

There are a number of different way to integrate SpamAssassin with Communigate Pro. Note that some of these are pretty old and haven't been modified recently.

scanspam.sh

Script to call Spam Assassin from CommuniGate Pro Rules v1.1 Ed Fang If you have any improvements, drop me a line at edfang@visi.net Thanks for Stefan Seiz for the original template

Script will call SpamAssassin spamc from CommuniGate. Since SA modifies the actual message, it must be re-delivered via the Submitted directory. Sneaky Header Tagging is used to prevent the message from being scanned again, and/or being caught in a loop is spamd fails.

# DATA
# Communigate Pro Rules 
# Any Recipient in     *@domain.com 
# Message Size  less than   32768 
# Header Field   is not     X-Spam-Status*

# ACTION 
# Execute       [STDERR] [FILE] [RETPATH] [RCPT] /var/CommuniGate/scanspam.sh 
# Discard 
# 
#  You must discard the message as the script will re-submit the marked message through the 
#  Submitted directory of CommuniGate.  If you don't, you'll get every message 
#  twice - once scanned, once clear through.  (which is a good way to test 
#  before actually discarding the message.  Stalker has asked that messages 
#  not be modified in the Queue directory, so it's just safer to play by their 
#  rules. 
# 
#  1.1 - Changed to run using gawk.  Highly advised as awk will occasionally 
#        crap out with trememdously long html lines. 
# 
#  Note: The global variables aren't used all over the place, so I'll clean that 
#  up in a later version.  I think there might be a more efficient awk script 
#  so any other awk gurus out there might be able to give me a better awk 
#  than the one I have (which skips everything until it matches Received 
#  and then to the end of the file.
