Hoping someone here can help. Running ubuntu 11.10 and latest ispconfig 3. I have a mailbox email@example.com that will be used for email piping. I'm trying to get the osticket WP plugin working with email piping but no joy. I've run through many posts and tried the following: Custom email filter recipe: to "|/var/www/clients/client4/web4/web/wp-content/plugins/zingiri-tickets/osticket/upload/api/pipe.php" This produces a rather hard to catch error in the mail.log vmail no recipient found in header .... I've tried creating a system user helpdesk, then adding a new alias helpdesk: "|/var/www/clients/client4/web4/web/wp-content/plugins/zingiri-tickets/osticket/upload/api/pipe.php" Then using cc "!helpdesk@localdomain" in custom rules (ispconfig). This actually gave me a proper message after an error as below: Jan 2 11:07:19 server1 postfix/sendmail: fatal: nobody(65534): No recipient addresses found in message header Jan 2 11:07:19 server1 postfix/local: 189A615A1F65: to=<helpdesk@localhost>, relay=local, delay=0.08, delays=0.02/0.01/0/0.05, dsn=2.0.0, status=sent (delivered to command: /var/www/clients/client4/web4/web/wp-content/plugins/zingiri-tickets/osticket/upload/api/pipe.php) But again, no ticket is created in osticket. No other errors in syslog or mail.log. Using redirect "helpdesk@localhost" also produces same result as above. At a loss here and would appreciate any suggestions.
