Hi, Possibly the error is in the email destination, inexistent user for example, or in the outlook.
Outlook or Outlook Express? Same version? Is a permanent error for this users? Any email sent for these customers is denied? Try send mail to self only? I have problems with Outlook with some customers, after install the last office service pack the problem solved, not xmail related. Don=B4t remember now, but AllowSmtpVRFY check the email, if i correct, try to set AllowSmtpVRFY to 0. Somebody speaks if I will be wrong. Run the xmail with -Sl parameter and check the log files under the "logs" folder.
