"Display-name" rewriting

[Sylvain Ferrand]

Hello,

I would like to overwrite the "display-name" (i.e. the sender
description string in the the From: field. - cf. RFC 5322 sec 3.4) set
by the MUA. Is it possible to rewrite the "display-name" (1) in the
"From:" header on a postfix server ?

Thanks in advance,

Sylvain Ferrand

/^From: (.*) <(.*)>$/ REPLACE From: blah <$2>

Only via a content filter or milter. There is at this time no feature
that allows you to match a given header address to a preferred display
name and munge the associated header address.

The use of "header_checks" for this is ugly, and would scale to only
a few tens to hundreds of individuals before the regexp table approach
starts to get rather expensive...

Finally, if munging, you should also munge "To" and "Cc", not just "From",
and that is outright impossible with regexp tables.

I misread this. Disregard my answer.
What you want to do needs to be done using content_filter or milter or
smtpd_proxy_filter.

My guess is that this is not what the OP is looking for. My bet is he
wants per-address display name rewrites, ...

This was exactly what i'm doing years a go.rewriting my users real name
defined in mysql database instead of their From: defined in MUA.
I've published the prototype i wrote here:

Sorry, it's in indonesian.i hope that articles lead you to some clues
