Here is what I do to spammers: Dear Sir or Madam, We were recently notified that you received Spam from one of our customers. We would like to notify you that his account has been terminated. If you have any other questions, please feel free to contact Interact Digital Technologies or visit our terms of service at: http://www.interactdigitaltechnologies.com/terms.htm Again, we are very sorry for any trouble this person has caused you. Sincerely, David Burns Interact Digital Technologies http://www.interactdigitaltechnologies.com I just wanted to share that with you! The id10t who spammed me even tried spoofing the from address to make it look as if it came from my own domain, so I forwarded it to them. Actually, how can one fix this? I am using Sendmail. Matt
