Could they be notifications that are being sent to a forged address, ala viruses? John Tolmachoff MCSE CSSA Engineer/Consultant eServices For You www.eservicesforyou.com -----Original Message----- From: Juan Ibarra [mailto:jibarra@xxxxxxxxxxx] Sent: Monday, June 16, 2003 11:25 AM To: [ExchangeList] Subject: [exchangelist] Email problems http://www.MSExchange.org/ Hello to all, One of my users has recently being getting several undeliverable messages to his inbox. Apparently from people that he never sent the emails to. He is very concerned about this. I am not an open relay for sure, so the other response that I have is that someone has probably hi-jacked his email address and is trying to send the emails as him. Can any one please give me an opinion on this and what would I need to do to stop this? Is changing his handle the only way out? Thanks in advance.
