Supported options include: --aa _p_l_a_i_n_t_e_x_t|_o_t_p|_s_a_s_l Tells ppooppppeerr which authentication mode is acceptable, _s_a_s_l enables SASL (RFC2222), and _o_t_p enables OTP (RFC1938) authenti- cation. 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 authentication. --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.
