PEAR::Mail_mimeDecode - no message-id

Hi all, I 've a problem with mimeDecode. It seems I can retrieve the message-id from some message. I use this code: ... $decoder = new Mail_mimeDecode($message); $params['include_bodies'] = TRUE; $params['decode_bodies'] = TRUE; $params['include_headers'] = TRUE; $params['decode_headers'] = TRUE; $structure = $decoder->decode($params); ... I get the others headers fields. I just can't get the message-id from some mails for example this one: From - Wed May 25 16:31:40 2005 X-Account-Key: account3 X-UIDL: 128-1036060041 X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 X-Kaspersky: Checked Return-path: <studenti-owner@liste.unimi.it> Received: from sunfire1.divtlc.unimi.it (sunfire1.divtlc.unimi.it [159.149.105.138]) by mailstudenti.unimi.it (iPlanet Messaging Server 5.1 (built May 7 2001)) with ESMTP id <0IA500D66GZX9G@mailstudenti.unimi.it>; Tue, 11 Jan 2005 12:25:23 +0100 (MET) Received: from liste.unimi.it (liste.unimi.it [159.149.105.13]) by sunfire1.divtlc.unimi.it (8.12.11/8.12.11) with ESMTP id j0BBBxnH023362; Tue, 11 Jan 2005 12:18:42 +0100 Received: from sympa by liste.unimi.it with local (Exim 3.35 #1) id 1CoJzC-0003XQ-00; Tue, 11 Jan 2005 12:14:55 +0100 Date: Tue, 11 Jan 2005 12:00:42 +0100 From: listastudenti@unimi.it Subject: [studenti] Secondo incontro per studenti To: studenti@liste.unimi.it Errors-to: studenti-owner@liste.unimi.it Reply-to: studenti@liste.unimi.it Message-id: <studenti.2@anonymous> MIME-version: 1.0 X-MIMEOLE: Produced By Microsoft MimeOLE V6.00.2800.1478 X-Mailer: Microsoft Outlook Express 6.00.2800.1478 Content-type: text/plain; charset=iso-8859-1 Content-transfer-encoding: 7BIT X-Priority: 3 X-MSMail-priority: Normal Precedence: list X-Loop: studenti@liste.unimi.it X-Sympa-To: studenti@liste.unimi.it X-PMX-Version: 4.7.0.111621, Antispam-Engine: 2.0.1.0, Antispam-Data: 2005.1.10.49 X-PMX-Version: 4.7.0.111621, Antispam-Engine: 2.0.2.0, Antispam-Data: 2005.1.10.49 X-PerlMx-Spam: Gauge=IIIIIII, Probability=7%, Report='NO_REAL_NAME 0, __CT 0, __CTE 0, __CT_TEXT_PLAIN 0, __HAS_MSGID 0, __HAS_MSMAIL_PRI 0, __HAS_X_LOOP 0, __HAS_X_MAILER 0, __HAS_X_PRIORITY 0, __MIME_VERSION 0, __SANE_MSGID 0' X-Validation-by: liste.cosp@unimi.it X-Sequence: 2 List-Id: <studenti@liste.unimi.it> X-No-Archive: yes Thanks for your help, Mattia.
