popper — POP3 server
|popper|| [-k] [-a |
popper serves mail via the Post Office Protocol. Supported options include:
- Tells popper which authentication mode is acceptable,
saslenables SASL (RFC2222), and
otpenables 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.
- Port to listen to, in combination with -i.
- Trace all commands to file.
- Set timeout to something other than the default of 120 seconds.
RFC1939 (Post Office Protocol - Version 3)
The server was initially developed at the University of California, Berkeley.
Many changes have been made as part of the KTH Kerberos distributions.
