Still having problems with masquerading

We currently have an internal email system using the domain
<internal.com> . Our regular domain is <example.com>. Up until a
month ago we were using sendmail and I thought I had figured out how to
do the masguerading of the internal domain. But I am getting some of
my users email bounced back because they are still showing in the
headers as
Sender : <user1@internal.com>.


mydomain = example.com
myorigin = $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain,
example.com,localhost.localdomain,internal.com

canonical_maps = hash:/etc/postfix/canonical

masquerade_domains = internal.com
------------------------
#postmap /etc/postfix/canonical
----------------------------------
/etc/postfix/canonical
@internal.com @example.com

Try adding this line:

local_header_rewrite_clients = static:all

Problem seems to have disappeared. I checked some of my clients and
the thunderbird ones and the evolution ones were not having a problem.
The problem was with one system which was running outlook out of a
number of systems. Don't know why it was happening, but I saw the
bounced email from the remote smtp server. But now everything that is
being sent from that client appears to be masked. I will look into the
use of your recommendation and if I can't find it in my Postfix book
I'll put it in there in case this comes up again.
