This is not a huge deal for web services mailing patches, because they 
just need to specify the `From:` header in the body of the patch. From 
`man git-am`:

  "From: " and "Subject: " lines starting the body override the 
  respective commit author name and title values taken from the headers.

So, a web service emailing patches can have:

  From jdoe@webserviceaddr.example.org
  From: J.Doe <jdoe@webserviceaddr.example.org>
  Reply-to: J.Doe <jdoe@corpaddress.example.com>
  Cc: jdoe@corpaddress.example.com
  Subject: [PATCH] Fix foo in bar

  From: J.Doe <jdoe@corpaddress.example.com>

  Signed-off-by: J.Doe <jdoe@corpaddress.example.com>

This *should* be kosher with legal requirements in most companies:

- the email traverses the corporate server when the cc is received, so 
  there is a log of it in their legally required auto-cc inbox
- all replies will be sent to the corporate server
- when the patch is applied, the commit will be properly listing the 
  corporate address

Only a very small subset of people have these, and it may still be not 
allowed by individual company's legal departments even when this is 
available.
