The original subject is: Nov 9 13:18:16 zenon postfix/cleanup[11310]: 3384E42508017: warning: header Sub ject: =?UTF-8?Q?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249?= from .. and there is no other postfix involved. > > Does postfix first decode the =?UTF-8? before matching? or did I miss > > something else? > > No, Postfix does not decode the subject. Using the _exact_ header displayed by postfix in its header 'warning': ZENON:~# postmap -q 'Subject: =?UTF-8?Q?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249?=' pcre:/etc/postfix/header_access_local REJECT nous savons gérer nos échéances! I get a match from postmap. Yet postfix does not block the message... Why?
