A coworker of mine is having trouble sending mail using SMTP authentication
with SSL encryption. Client is Outlook 2000 on windows XP Home, server is sendmail 8.12.11 He can receive mail find; however sending does not work and "xxxx.clientip.com did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA is logged on the sendmail server. Other clients using Outlook 2003 and XP pro do not have issues. I was going to give him a Outlook 2003 CD in the hopes that it would solve the problem, but if anyone has a KB article reference or any other suggestions, much appreciated.

I haven't used outlook 2000 in a long time, but I have a nasty suspicion
that it doesn't support SSL/TLS on port 587. Instead Outlook 2000 will want to do setup a secure connection on 25 or go old school with port 465 (SSMTP). Just so you know, Outlook 2003 didn't get its act together for SSL/TLS until Office 2003 SP2. "Edward Ray" wrote in message ... "neo [mvp outlook]" wrote in message ...
