802 | Chapter 21: The D (Define a Macro) Configuration Command
When the V8 sendmail daemon receives a network connection request (and if the
Timeout.ident option, ?§24.9.119.13 on page 1104, is nonzero) it attempts to connect to the
originating host??™s identd service. If the originating host properly supports identification,
sendmail reads the login name of the user who initiated the connection (although sendmail
will read whatever the other side sends, including garbage). The sendmail program then
appends an @ and the originating hostname to what it interprets as the username.
