+relies on the underlying TCP/IP protocol to reach the server host.
+Transient links are commonly established directly to a mail host and are
+relatively secure channels to communicate. When other routes exist, or
+when a transient link is established to a different remote host, your
+username and password may be vulnerable to snooping when daemon mode
+automatically polls for mail.
+.sp
+This option may be used to specify a connection IP address (or range)
+for a system TCP/IP interface. When the link is not up or is connected
+to a different host, polling will be skipped. The format is:
+.sp
+ interface/iii.iii.iii.iii/mmm.mmm.mmm.mmm
+.sp
+The field after the first slash is the acceptable IP address and the
+field after the second slash is a mask which specifies a range of IP
+addresses to accept. If no mask is present 255.255.255.255 is assumed
+(i.e. an exact match).

+.B \-M interface, --monitor interface
+Daemon mode can cause transient links which are automatically taken down
+after a period of inactivity (e.g. PPP links) to remain up
+indefinitely. This option identifies a system TCP/IP interface to be
+monitored for activity. After each poll interval, if the link is up and
+no other activity has occurred on the link then the poll will be
+skipped. This option is currently only supported under Linux.
