Supporting Outlook "Secure Password Authentication&quot

Hi, I've been beating my head against a wall trying to find a way to support Outlook and Outlook Express users sending and receiving mail through my 10.3.3 Server. The problem is simple: 1. I won't allow plain text password authentication. At all. 2. postfix and cyrus don't have an obvious way to support NTLM authentication (which is what I understand is meant by the "Secure Password Authentication" option in Outlook [Express] ). The password server has all the protocols enabled: [code:1:552a2466aa]silver:/ root# NeST -getprotocols "SMB-NT" Enabled Hash "SMB-LAN-MANAGER" Enabled Hash "MS-CHAPv2" Enabled Plain "CRAM-MD5" Enabled Hash "WEBDAV-DIGEST" Enabled Hash "APOP" Enabled Plain[/code:1:552a2466aa] Any ideas what to do now? Thanks, Terry
