Some ISP's (Internet Service Providers) block you using their SMTP servers when you aren't connected to their network. MX Tools provides an outbound SMTP service that works from any network, any location called MX Outbound (MXO). MXO is an authenticated SMTP mail relay (SmartHost) service.

Some ISP's even block, filter or redirect standard SMTP (Port 25) traffic. So MX Tools provides alternative SMTP ports to use.
