Hi, The following rule has served us well for a long time: /^Subject:.*<Urgent\/>.*/ FILTER relay...
Today, it missed the following <<Feb 9 09:58:27 mail13 postfix/cleanup[8310]: A1D63200A290: warning: header Subject: =?iso-8859-1?Q?WG:_Jugement_int=E9gral_Frenner_Pierre_Alain,_13.11.1977_<Urg e?=? =?iso-8859-1?Q?nt/>_TestABC_XYZ?= from mail01....>> It seems that outlook after approx. 55 characters terminates the encoding and immediately restarts it. In the above sample it breaks the keyword "Urgent" in 2 pieces. Is there a way to apply a FILTER relay on a subject pattern where the subject is decoded?? A similar discussion was already in http://marc.info/?l=postfix-users&m=141047275418893&w=2 but in the end was not solving the encoding question. Many thanks for any hints in advance Ralf
