[otrs] LDAP look-up customer

Hi, When a customer sends a mail he isn't looked up in the LDAP. This is very annoying cause for every mail that we receive, we have to click 'customer', 'search user', 'update'. Could this look-up be integrated in the fetchmail script. So once the mails are fetched al the users known to the LDAP are associated with their LDAP entry? greets, Wouter
