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.
- CGPSA: http://www.tffenterprises.com/cgpsa/ (should work on both Linux and Windows)
- CGPAV: http://program.farit.ru/doc/cgpav.html
- sa-cgp: ftp://ftp.vsu.ru/pub/apps/CGP/sa-cgp.c
- scanspam.sh (Linux only see below)
- cgSpamAssassin: https://github.com/bret-miller/cgSpamAssassin (should work on both Linux and Windows)
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.

# the actual message, it must be re-delivered via the Submitted directory. |
...
# Sneaky Header Tagging is used to prevent the message from being scanned |

...
# 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. |
