An example replacement given the header
X-MyHeader: this is it
# /etc/postfix/header_checks
/^(X-MyHeader: .*) is (.*)$/
REPLACE $1 was $2
end result:
X-MyHeader: this was it
While the concept is simple, it can be hard to get right[1],
so one must consider if it's worth doing.
So, what are the headers you are trying to transform? Why do
they say localhost and why do you think they shouldn't? Maybe
removing the offending header with an IGNORE rule would be better?
Is there anything, for the headers, that is like sed?
Not that I'm aware of. Some milter might exist with such a
feature.
[1] You need to be careful to only match the intended header,
only replace the intended text, and never mangle headers
supplied by other systems. There are resources for writing
regular expressions on the web that will generally apply to
postfix.
