NAME
     popper -- POP3 server

SYNOPSIS
     popper [-k] [-a plaintext|otp|sasl] [-t file] [-T seconds]	[-d] [-i]
	    [-p	port] [--address-log=file]

DESCRIPTION
     popper serves mail	via the	Post Office Protocol.  Supported options in-
     clude:

     -a	plaintext|otp|sasl
	     Tells popper which	authentication mode is acceptable, sasl	en-
	     ables SASL	(RFC2222),  and	otp enables OTP	(RFC1938) authentica-
	     tion. Both	disable	plaintext passwords.

     --address-log=file
	     Logs the addresses	(along with a timestamp) of all	clients	to the
	     specified file. This can be used to implement POP-before-SMTP au-
	     thentication.

     -d	     Enables more verbose log messages.

     -i	     When not started by inetd,	this flag tells	popper that it has to
	     create a socket by	itself.

     -k	     Tells popper to use Kerberos for authentication. This is the tra-
	     ditional way of doing Kerberos authentication, and	is normally
	     done on a separate	port (as it doesn't follow RFC1939), and
	     should be used instead of using SASL.

     -p	port
	     Port to listen to,	in combination with -i.

     -t	file
	     Trace all commands	to file.

     -T	seconds
	     Set timeout to something other than the default of	120 seconds.

STANDARDS
     RFC1939 (Post Office Protocol - Version 3)

AUTHORS
     The server	was initially developed	at the University of California,
     Berkeley.

     Many changes have been made as part of the	KTH Kerberos distributions.
