Popbindaddr Option

The  MSHTTP option specifies the IP address to which to bind outgoing POP connections when collecting external mail. If unset, defaults to the value of listenaddr.

Note that the  MSHTTP option controls whether or not such external collection is permitted, and the   MSHTTP option specifies a maximum on the message size that may be collected.
