No, not for MS SMTP alone; believe me, we've done much research on the subject in hopes of writing just that AUTH plug-in for an IMail database. There are hitches in the way SMTP event sinks are processed (in fact, one major hitch is due to an error in the MSDN docs that has never been updated with correct info) that make them suitable for just about anything in the envelope _but_ SMTP AUTH transactions. It is indeed possible to write alternate authentication packages for the Windows platform as a whole, and these are comparatively well-documented. but IME this is some of the most advanced systems programming around, and very difficult to code safely. It's also possible, quite simply as far as the client side goes, to use Kerberos from MS SMTP, but on the server side this requires a KDC capable of issuing tickets for credentials from either the IMail registry or ODBC; since the only open-source KDC (MIT) is *nix-based, this would be mean hacking (and running) a *nix-based KDC to use a Windows-based datasource. This is not a drop-in solution. :) --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ http://www.mailmage.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
