Since this is Windows, I would first consider installing/using the IIS SMTPSVC mailer that is part of Windows on the LISTSERV machine and use that for outgoing mail, completly bypassing the issues with your Exchange server. There is a paper on how to do this: Using the Microsoft IIS SMTP Service for LISTSERV Deliveries http://www.lsoft.com/resources/whitepaper-download.asp?id=209 You may need to make some firewall and/or DNS changes (any machine used as a sending mail server needs proper A and PTR records) for this to work properly but it may be the fastest/easiest solution. ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
