Keep it on the list, that way others can jump in when I have to go back to my beer and watching CSI with the woman... O I see what you want. You want to stop your people sending other people attachments FROM a hotmail or yahoo account. Good luck, its part of their mail setup and if they allow it, then its allowed. You could block access to the hotmail and yahoo websites so they cant check their hotmail from work! G It's web mail, through http, not through SMTP, Which message screener can do this???can you tell me the name???
