Zendesk doesn't recognise how the ticket was received if the e-mail was in BCC.

Strange is that the ticket is created correctly, but since the address is used in BCC, the "via" in the ticket isn't correct (it'll be the native adress of Zendesk)

There triggers and other ways to automate some processes in Zendesk are impossible.

I can't believe that BCC isn't supported by Zendesk. Such a basic function of e-mail.
