Our LSMTP (LSMTP Lite for Windows NT v1.1a) is having a problem sending e-mail to a specific domain (VISUS.JNJ.COM), but our corporate e-mail system gateway (IMA) is able to send to that domain with no problem. Below is a clip from the LSMTP log file. These entries fill the log file for the last five days, so it's been trying every 10 minutes since last week. It finally gave up today. Any help would be very much appreciated.
