Hi Frans We had a similar problem and used a small script to add the X-OTRS header to the email before piping it to the postmaster. The script does a lookup for the mail address in the customer db and adds the X-OTRS-FreeKey and FreeText to the Mail-header. Works like charm.

The case reference field I assume could be added through SysConfig as FreeText. Been struggling with this, how to go about and add an additional field (that could be entered/modified)? Perhaps anybody is using a similar field? gr, Frans
