When sending emails specifying topics that it applies to, is there a way
to have the listed topics (left of the colon) stripped from the Subject
line?

--------
Example:

From: [log in to unmask]
To: [log in to unmask]
Subject:   Animals,Sports,Stocks: This is the subject line for this
sample email!
--------

I would like for only the subject line (all text right of colon) to
show...Is there any way to do this?
