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.
