Every day I get an error emailed to me from Cron Daemon stating: Code: /usr/bin/update-relay-recipients.sh: line 4: postmap: command not found Here is my crontab entry: Code: 30 2 * * * /usr/bin/update-relay-recipients.sh And the contents of /usr/bin/update-relay-recipients.sh: Code: #!/bin/sh /usr/bin/getadsmtp.pl cd /etc/postfix postmap relay_recipients If I run the script manually I don't get any errors. Ideas? By the way, Rocky, great tutorial! I'm loving the 28,000+ connections that are bounced before ever getting to my Exchange server. Spam is almost yesterday's news after running this snake for a week.
