popper

POPPER(8)                                                   BSD System Manager's Manual                                                  POPPER(8)

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 include:

     -a plaintext|otp|sasl
             Tells popper which authentication mode is acceptable, sasl enables SASL (RFC2222),  and otp enables OTP (RFC1938) authentication.
             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
             authentication.

     -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 traditional 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.
