IP Stripping (replace)

[Martin Bock]

Hi,

Ich hatte mal was zusammengeschrieben und getestet, bei mir funktioniert
das:

/^(Received: from)(.*)\s*(by.*)(with ESMTPSA)(\s*)(.*)/ REPLACE $1
localhost (localhost [127.0.0.1]) $5$3$4$5$6

Passt natürlich auf meine Header:
Received: from [1.2.3.4] (5-6-7-8.hostname.tld [5.6.7.8])
        by hostname (Postfix) with ESMTPSA
        for <user at hostname>; Sun, 17 Jul 2016 19:30:53 +0200 (CEST)

Jetzt habe ich mein Pattern kurz angepasst, bekommt man vermutlich
eleganter hin aber es scheint zu funktionieren und erkennt deinen Header
(oberflächlich getestet auf regex101.com und per postmap):
/^(Received: from)(.*)\s*(\(.*\)\s*){3}(by.*)(with ESMTPSA)(\s*)(.*)/

Gruß Martin
