My institution stream-edits incoming mail to add this text to the top of every email from external sources:
\n
[EXTERNAL to MyCompany received message]
\n
It makes the summary views unhelpful, since the first few lines of most emails are now boilerplate. Is there a way to run the incoming mail on the client end though sed or something to conditionally remove the first few lines if they match this unwanted text?

I use Mac Mail to access an Exchange mailbox.
