Hi, I have a problem in my FC4 system. System info: kernel: 2.6.16-1.2096_FC4 sendmail: 8.13.6-0.FC4.1 dovecot: 0.99.14-4.fc4 Recently, users say that they cannot use Outlook to send emails out if they set SSL connection with port 587 for outgoing server and 993 for incoming server. Then, I tested a guest account on several computers. The strange thing is when I test it on my PC and another one, everything works well. However, when I test it on other 2 computers (all are Win XP pro, with Outlook 2003), I cannot send emails out. The error message from Outlook is: Task 'Matt Morp - Sending' reported error (0x800CCC7D) : 'Your outgoing (SMTP) server does not support SSL-secured connections. If SSL-secured connections have worked in the past, contact your server administrator or Internet service provider (ISP).' The system log shows: Sep 22 13:27:22 morpheus sendmail[27813]: k8MFRMjY027813: [128.252.85.77] did not issue MAIL/EXPN/VRFY/ETRN during connection to MSA All computers are in our campus and in the same subnet. Also, users didn't complain before yesterday, but I didn't change the system recently. My questions are: 1. What does the above message mean? 2. Why the same account can send emails from two PCs, but not from other PCs when all use Outlook 2003 with the same settings (SSL connection, port 587 for outgoing, etc.)? Thanks! Hongwei Li
