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.

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