popper — POP3 server


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


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.
Logs the addresses (along with a timestamp) of all clients to the specified file. This can be used to implement POP-before-SMTP authentication.
Enables more verbose log messages.
When not started by inetd, this flag tells popper that it has to create a socket by itself.
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.

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

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