If you can define what you mean by "outgoing mail" you can put
conditions into the expansion string. For example,
${if match{$sender_address}{^.*@???}{......} fail}
This particular example doesn't necessarily match "outgoing mail"
though: consider a message sent by one of your users to a remote host
which then forwards it back to somebody else in your domain. You could
test $sender_host address to check for this.

There is no env-from header. Do you mean the envelope's "From" address?
This is often called the "envelope sender". Because this is not an RFC822
header, you cannot access it via headers_remove / headers_add.
I do not understand "GMX", I'm afraid.
