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.

AUTHORS
The server was initially developed at the University of California,
Berkeley.
Many changes have been made as part of the KTH Kerberos distributions.
