149 * imap4d supports PREAUTH mode.
150
151 Three mechanisms are provided for authentifying the connection in
152 PREAUTH mode:
153
154 1. stdio - PREAUTH mode is enabled automatically if imap4d is started
155 from command line in interactive mode (-i command line
156 option). The current login name is used as the user name.
157
158 2. ident - The remote machine is asked about the requester identity
159 using the identification protocol (RFC 1413). Both plaintext and
160 DES encrypted replies are understood.
161
162 3. prog - Imap4d invokes an external program to authenticate the
163 connection. Four arguments are supplied to the program:
164
165 1) Remote IP address in dotted-quad notation;
166 2) Remote port number;
167 3) Local IP address (currently "0.0.0.0");
168 4) Local port number.
169
170 If the connection is authenticated, the program should print the
171 user name, followed by a newline character, on its standard
172 output and exit with code 0.
173
174 Otherwise, it shoud exit with a non-zero exit code.
