I edited ~/.forward as
So I did some research...
Seems sendmail 8.11.6 with RH71 is using procmail not mail for local
delivery thing. So it not reading .forward.
So I edited ~./procmailrc
still no forwarding.
I wondering if sendmail 8.11.6 on RH71 disabled forwarding for security
and spam reason?
I did the following too
# ln -s /usr/bin/procmail /etc/smrsh
according to redhat faq
