era eriksson seems to have said:
The backticks will actually substitute all newlines in the output of
the cat with a space. Probably not what you want. Try this (swiped
from an old post by wotan(_at_)netcom(_dot_)com, I think):
SENDER=`formail -rtzx To:`
This is neat! As an experiment
I just ran this command on a few old folders:
formail -s formail -rtzx To: < $oldfolder | sort -u
... and it builds a list of people and lists which have
sent me mail.
