Undeliverable

Hi Experts,
SBS 2003 , One of my users are getting Undeliverable messages  for e-mails she did not send out. She is getting about 10 a minute. My guess is that some spammer is using the E-Mail address. Would this be coming from my server that I can block or is it coming from the outside?
Thank You,
John

Most probably it is the spoof emails sent by spammers. I had a similar issue where users were receving all sorts of spam emails from internal addresses. The best way to deal with this issue is by setting up SPF record. Check this:
