If it's helpful, I've tried replacing the pipe script's contents with the following: ##################################################################### #!/bin/bash /usr/lib/dovecot/deliver -d "sa-train...@example.com" -m "Training.$mode" -p /var/vmail/gtube.txt # Exit with "success" status code. exit 0 ##################################################################### And still, the message never arrives when I drag a message from "Inbox" to "Spam" in the IMAP client, despite the messages logged to syslog, which "all seem to be correct". Yet, if I do this using the above content for the script, the "gtube" message is delivered successfully: # su vmail $ /usr/local/bin/sa-learn-pipe-test.sh The message arrives in the Inbox, presumably because -m "Training.$mode" does not "resolve" to anything, and per the documentation, the delivery destination will default to the Inbox in such cases. What's wrong with my the custom pipe script to which I posted a link in my previous message, I wonder? Thanks again for any assistance, -Ben
