— Imap4d Conf: tls-required bool

Require successful STARTTLS command before entering authentication phase.

— Imap4d Conf: preauth mode

Configure PREAUTH mode. Valid arguments are:

prog:///program-name

Imap4d invokes an external program to authenticate the connection. The command line is obtained from the supplied string, by expanding the following meta-variables:

${client_address}

Remote IP address in dotted-quad notation;

${client_port}

Remote port number;

${server_address}

Local IP address;

${server_port}

Local port number.

If the connection is authenticated, the program should print the user name, followed by a newline character, on its standard output and exit with code ‘0’.

Otherwise, it should exit with a non-zero exit code.

ident[://:port]

The remote machine is asked about the requester identity using the identification protocol (RFC 1413). Both plaintext and DES encrypted replies are understood. Optional port specifies the port to use, if it differs from the default ‘113’. It can be either a decimal port number or a symbolic name of a service, listed in /etc/services.

stdio

PREAUTH mode is enabled automatically if imap4d is started from command line in interactive mode (-i command line option). The current login name is used as the user name.

— Imap4d Conf: preauth-only bool

If bool is ‘true’, use only preauth mode. If unable to setup it, disconnect immediately.

— Imap4d Conf: ident-keyfile file

Set DES keyfile for decoding encrypted ident responses. Used with ‘ident://’ preauth mode.
