It really boils-down to the fact that I can call the following on the command-line and it functions as expected:

su vmail -c '/usr/lib/dovecot/deliver -a "sa-training@example.com" -d "sa-training@example.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-25794.txt"'

Yet, when I attempt to do the exact same thing from within the pipe script that Dovecot Antispam calls, I receive exit code 75 from deliver/dovecot-lda and absolutely nothing is logged, with exception of the information of which I'm already aware (logged to syslog).

Have you also checked the environment variables? I think dovecot-lda gets some information from them. Also, it's possible the PATH or some other critical environment variables is different, causing the difference in outcome.

Thanks for the reply, Joseph. I appreciate your time.

I added debugging output to the script, which now prints the environment variables. My script now outputs the following:

25985-start (--spam) ENV value is: DOVECOT_PRESERVE_ENVS=TZ SSL_SOCKET_COUNT=0 DOVECOT_CHILD_PROCESS=1 CONFIG_FILE=/var/run/dovecot/config SOCKET_COUNT=1 PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin PWD=/var/vmail/example.com/ben CLIENT_LIMIT=1 GENERATION=9 DOVECOT_VERSION=2.0.19 SHLVL=1 LOG_SERVICE=1 SERVICE_COUNT=1 _=/usr/bin/env Checking if the command-line input argument string (--spam) contains the string "ham" or "spam" Mode is "SPAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training@example.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-25985.txt"' Exit status was 75 25985-end

Does anything jump-out at you?

Thanks again,
