popper - POP3 server
SYNOPSIS[-k ] [-a plaintext | otp | sasl ] [-t file ] [-T seconds ] [-d ] [-i ] [-p port ] [--address-log= file ]
DESCRIPTIONserves mail via the Post Office Protocol. Supported options include:
- -a plaintext | otp | sasl
- Tells 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.
- Enables more verbose log messages.
- When not started by inetd, this flag tells that it has to create a socket by itself.
- Tells 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.
STANDARDSRFC1939 (Post Office Protocol - Version 3)
AUTHORSThe server was initially developed at the University of California, Berkeley.
Many changes have been made as part of the KTH Kerberos distributions.
