Hi, I can't seem to get postfix to match that header:
Subject: =?UTF-8?Q?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249?= with this /etc/postfix/header_check entry (PCRE): /^(Subject: =\?UTF-8\?Q\?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249\?=)/ REJECT yet a: postmap -q 'Subject: =?UTF-8?Q?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249?=' /etc/postfix/header_check does match. Does postfix first decode the =?UTF-8? before matching? or did I miss something else? Thanks, Here are log entries: Jul 20 09:13:47 zenon postfix/smtpd[14052]: AC5BA5B93D146: client=aussmtpmrkps312.us.dell.com[143.166.224.212] Jul 20 09:13:48 zenon postfix/cleanup[14960]: AC5BA5B93D146: message-id=<2301567.1279610009277.javamail.ora...@ausgoprdap08.us.dell.com> Jul 20 09:13:48 zenon postfix/cleanup[14960]: AC5BA5B93D146: warning: header Subject: =?UTF-8?Q?Vos_Factures_arrivant_a_=C3=A9ch=C3=A9ance_-_FR0905249?= from aussmtpmrkps312.us.dell.com[143.166.224.212]; from=<x...@dell.com> to=<x...@example.com> proto=ESMTP helo=<aussmtpmrkps312.us.dell.com> Jul 20 09:13:48 zenon postfix/cleanup[14960]: AC5BA5B93D146: warning: header Content-Type: application/pdf; ??name=Document_FR_REL_ENTP_9230813_2010-07-20_PR1.pdf from aussmtpmrkps312.us.dell.com[143.166.224.212]; from=<x...@dell.com> to=<x...@example.com> proto=ESMTP helo=<aussmtpmrkps312.us.dell.com> Jul 20 09:13:48 zenon postfix/cleanup[14960]: AC5BA5B93D146: warning: header Content-Disposition: attachment; ??filename=Document_FR_REL_ENTP_9230813_2010-07-20_PR1.pdf from aussmtpmrkps312.us.dell.com[143.166.224.212]; from=<x...@dell.com> to=<x...@example.com> proto=ESMTP helo=<aussmtpmrkps312.us.dell.com> Jul 20 09:13:48 zenon postfix/qmgr[6879]: AC5BA5B93D146: from=<x...@dell.com>, size=14508, nrcpt=1 (queue active) Jul 20 09:13:48 zenon postfix/local[14971]: AC5BA5B93D146: to=<x...@example.com>, relay=local, delay=18, delays=18/0/0/0.27, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail -a "$EXTENSION") Jul 20 09:13:48 zenon postfix/qmgr[6879]: AC5BA5B93D146: removed
