Hi Markus,

In the first place I'd try to find the origin of this line.
Exim doesn't know about any such line, the X- prefix indicates, that
this isn't a standard header line.

Hm. This is questionable practice, but probably to the topic we should
discuss about. (I'm using a static and well known mail address for decades now.)

So, probably Squirrel isn't the origin of this header.

What directive you're talking about?
> Does exim only accept customized headers when called from /usr/sbin/exim4?

You can ask exim to remove any header you want. Check the docs for
remove_header (ACL)
and
headers_remove (routers, transports)
