NAME

popd - The POP server

SYNOPSIS

/usr/lib/mh/popd [-p portno]

FLAGS

-p portno
Overrides the default TCP port.

DESCRIPTION

The popd server implements the Post Office Protocol (POP),  as  described in  RFC1081  and RFC1082.  Basically, the server listens on the TCP port named pop for connections. When it receives a connection request from a client, it performs the following functions:

       •Checks for client authentication by searching the POP password file in /usr/spool/pop. 

       •Sends the client any mail messages it is holding for the client. (The server holds the messages in /usr/spool/pop.) 

For historical reasons, the MH POP defaults to using the port named pop (port 109) instead of its newly assigned port named pop3 (port 110). 

To determine which port MH POP is using, check the value of the POPSERVICE configuration option. (You can display the POPSERVICE configuration option by issuing any MH command with the -help option.)  This option shows the service port name.  To find the port number, look in the /etc/services file for the service port name assigned to the POPSERVICE configuration option.  The port number appears beside the service port name. 

FILES
