Thanks. That isn't what I was trying to do here, but something I might 
do in the future. Here the two patches were separate, nit part of the 
series. I got confused in that I thought the mail wasn't getting set 
and tried a few different varients of the --smtp-server= option, most 
of which actually worked.

Can you set up your config to do that automatically or are you supposed 
to do that manually for each commit to make sure you really mean it?

In this case, one patch is trivial and the other needs to be reworked, 
so I doubt it matters.
