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

     --aa _p_l_a_i_n_t_e_x_t|_o_t_p Fl0_0Fl1_1Fl2_2Fl3_3Fl4
             Tells ppooppppeerr which authentication mode is acceptable, _s_a_s_l en-
             ables SASL (RFC2222),  and _o_t_p enables OTP (RFC1938) authentica-
             tion. Both disable plaintext passwords.

     ----aaddddrreessss--lloogg==_f_i_l_e
             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.

     --dd      Enables more verbose log messages.

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

     --kk      Tells ppooppppeerr 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.

     --pp _p_o_r_t
             Port to listen to, in combination with --ii.

     --tt _f_i_l_e
             Trace all commands to file.

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

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

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