SMTP and GroupWise

My client is using GroupWise to relay *without* having relay turned on and it needs/uses an authenication that is different from the regular SMTP. Here is a trace of a message that went through: 02/11/2004 06:55:27 SMTP to rcpt: Al Smith <Al.Smith@calgery.com> 02/11/2004 06:55:29 < +OK GroupWise POP3 server ready 02/11/2004 06:55:29 > USER scan01 02/11/2004 06:55:29 < +OK 02/11/2004 06:55:29 > PASS ******* 02/11/2004 06:55:29 < +OK 02/11/2004 06:55:29 > QUIT 02/11/2004 06:55:29 < +OK GroupWise POP3 server signing off 02/11/2004 06:55:29 Authenticated at POP Host: mailman.cd-hq.com 02/11/2004 06:55:31 < 220 mailman.cd-hq.com GroupWise Internet Agent 6.5.1 Copyright (c) 1993-2003 Novell, Inc.
