Typically used for sending mail to. 18/* .IP MAIL_ADDR_MAIL_DAEMON 19/* The mailer-daemon handle. Typically used to bring bad news. 20/* .IP MAIL_ADDR_EMPTY 21/* The empty mail address. This refers to the postmaster on the 22/* local machine. 23/* .PP 24/* mail_addr_double_bounce() produces the fully-qualified version 25/* of the local double bounce address. 26/* 27/* mail_addr_postmaster() produces the fully-qualified version 28/* of the local postmaster address. 29/* 30/* mail_addr_mail_daemon() produces the fully-qualified version 31/* of the local mailer-daemon address. 32/* CONFIGURATION PARAMETERS 33/* double_bounce_sender, the double bounce pseudo account. 34/* myhostname, the local machine hostname. 35/* BUGS 36/* Addresses are constructed by string concatenation, instead of 37/* passing them to the rewriting service. 38/* LICENSE 39/* .ad 40/* .fi 41/* The Secure Mailer license must be distributed with this software. 42/* AUTHOR(S) 43/* Wietse Venema 44/* IBM T.J.
