# Based on implementation of @JoshData (initially by @mkropat) for Mail-in-a-Box Project
# https://github.com/mail-in-a-box/mailinabox
# Remove the first line of the Received: header. Note that we cannot fully remove the Received: header
# because OpenDKIM requires that a header be present when signing outbound mail. The first line is
# where the user's home IP address would be.
#/^\s*Received:[^\n]*(.*)/ REPLACE Received: from authenticated-user (mail.898.ro [127.0.0.1])$1
# Remove other typically private information.
#/^\s*User-Agent:/ IGNORE
#/^\s*X-Enigmail:/ IGNORE
#/^\s*X-Mailer:/ IGNORE
#/^\s*X-Originating-IP:/ IGNORE
#/^\s*X-Pgp-Agent:/ IGNORE
# The Mime-Version header can leak the user agent too, e.g. in Mime-Version: 1.0 (Mac OS X Mail 8.1 \(2010.6\)).
#/^\s*(Mime-Version:\s*[0-9\.]+)\s.+/ REPLACE $1
# Remove Postfix from headers
/^(.*)\(898MTA\)(.*)/ REPLACE ${1}${2}
