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 at 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,
