What is that Six-Seven there?

/usr/include/sysexits.h:#define EX_NOUSER       67      /* addressee unknown */

It is a user-unknown bounce, and a local copy.

"The mail you are sending your request from, kris@koehntopp.de, is not the mail that is registered for your account, kris-ourcompanyname@koehntopp.de"

"That is correct. The mail you are sending your answer from, do-not-reply@ourcompanyname.com, is also not the mail address you want me to send my shit to, support@ourcompanyname.com, so what exactly is the problem?"
