Problem: I need to send emails from a PHP script using sendmail. Hotmail files the emails as "junk mail". I don't know how to persuade it to accept the emails as legitimate.

Here are the message headers, as received by Hotmail:

X-Message-Status: n X-SID-PRA: OTRS <otrs@otrs.ldtsystems.com> X-SID-Result: TempError X-Message-Info: 6sSXyD95QpX+v14ZO+UwZtOwu2A5j8tJDHnvmHq80q8= Received: from google.com ([207.97.226.194]) by mc1-f2.hotmail.com with Microsoft SMTPSVC(6.0.3790.211); Sat, 15 Jan 2005 16:05:13 -0800 Received: (from apache@localhost) by google.com (8.11.6/8.11.6) id j0G057F09082; Sat, 15 Jan 2005 19:05:07 -0500 Date: Sat, 15 Jan 2005 19:05:07 -0500 Message-Id: <200501160005.j0G057F09082@google.com> To: Mickey Phoenix <mickey_phoenix@hotmail.com> Subject: the subject From: OTRS <otrs@otrs.ldtsystems.com> Reply-To: <otrs@otrs.ldtsystems.com> Return-Path: otrs@otrs.ldtsystems.com X-OriginalArrivalTime: 16 Jan 2005 00:05:13.0997 (UTC) FILETIME=[0D7CE3D0:01C4FB5F] Sample message body goes here.

Can anyone tell me why Hotmail might be rejecting this?

Thanks!
