Grep for 'mail.warn' as well, and grep for the timestamp in the file to which warning messages are logged, if indeed it is a different file. If your system logs all mail messages to the same file, look for a warning message around the time stamp in question. > Once you find the mail error file on your system grep for the time stamp > above, 20:09:xx. Report the error. If you are not already, you need to be familiar with how your operating system logs various messages, and to what files. -- Stan
