On outbound mail I've noticed this header that, for my needs, is 'a bit
too much detail' insofar as revealing the internal IP of the client:
Received: from munged.com ([x.x.x.x]:52225
helo=[192.168.5.x]) by host.munged.com with esmtpsa
(TLSv1:AES256-SHA:256) (Exim 4.71) (envelope-from
<postmaster@???>) id 1ODwx4-0000zG-Oy for
recipient@???; Mon, 17 May 2010 10:49:34 +0100
What is the best approach to removing the header line detailing from
outbound smtpa/esmpta but not removing similar items from inbound? I've
had a quick look at filters and 'remove_header' but before I get bogged
down in this I would like a reassuring 'that's the right way to go'
nudge :-)
