 When upstreaming work we have done to a project which uses an e-mail based workflow there might be some pitfalls along the way.
 Our attribution should be in place (namingly the use of the company e-mail address as git author and maybe the signed-off-by), but sending the patches via Outlook/Exchange is not possible as the server side is known to mangle the e-mail format and patches would no longer apply.
