[otrs] Autoresponses not working

Hello, I've got a problem with autoresponses. I've set up many queues / subqueues and dispatching via X-OTRS-queue header on my trusted postmaster account. I've created an autoresponse for default reply / new ticket and set it as the default reply for my queues. Then I open a ticket via form inserting the needed headers. The ticket is created by OTRS and queue/subqueue dispatching works as expected, but the customer does not receive any autoresponse. What could it be? -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: new guy cross-connected phone lines with ac power bus.
