How do I correct spoofing problem on two mailboxes of 15
Posted on 2009-02-12
We have a IBM Server with Windows 2003 with Service 2 and Exchange Server 2003 with full update of Microsoft.
Our user have MS Outlook 2003 and Windows Xp, full update.- MS Exchange server have a SMTP connector for delivery the email without autenticartion of outgoing mail options
Well, we have spoofing problem on two of 15 mailboxes.- Every days these two users receive 5 or 8 spoofed mail.
My question is:
1.- Why only these two user have infected?
2.- Why I need to do for correct this situation?
