One possible solution comes into my mind, but it requires much work on several sides.

1. Agent Mike must send his mail directly through your company's mail server, while authenticating himself in a secure way (if that can be said in the case of SMTP).
2. The mail server, seeing this, should set an e-mail header, like X-OTRS-ThisMailIsActuallyFromAnAgent.
3. An OTRS PostMaster Filter script should set the article type to Agent-mail-external (or whatever)

Again, this requires a lot of effort, and maybe your environment can or can not do this at all. I wish you luck :)

Best,
Gergely
