Minimum system requirements
To use the e-mail functionality, the MFP must be connected to an IP-based server that
has simple mail transfer protocol (SMTP). This server can either be on the local area
network or at an outside Internet service provider (ISP). HP recommends tha tthe MFP
be located on the same local area network (LAN) as the SMTP server. If you are using
an ISP, you must connect to the ISP by using a digital subscriber line (DSL) connection.
If you are obtaining e-mail services from an ISP, ask the ISP to provide the correct
SMTP address. Dial-up connections are not supported. If you do not have an SMTP
server on your network, third-party software is available that allows you to create an
SMTP server. However, purchase and support of this software is your responsibility.
