Typically used for sending mail to. 20 /* .IP MAIL_ADDR_MAIL_DAEMON 21 /* The mailer-daemon handle. Typically used to bring bad news. 22 /* .IP MAIL_ADDR_EMPTY 23 /* The empty mail address. This refers to the postmaster on the 24 /* local machine. 25 /* .PP 26 /* mail_addr_double_bounce() produces the fully-qualified version 27 /* of the local double bounce address. 28 /* 29 /* mail_addr_postmaster() produces the fully-qualified version 30 /* of the local postmaster address. 31 /* 32 /* mail_addr_mail_daemon() produces the fully-qualified version 33 /* of the local mailer-daemon address. 34 /* CONFIGURATION PARAMETERS 35 /* double_bounce_sender, the double bounce pseudo account. 36 /* myhostname, the local machine hostname. 37 /* BUGS 38 /* Addresses are constructed by string concatenation, instead of 39 /* passing them to the rewriting service. 40 /* LICENSE 41 /* .ad 42 /* .fi 43 /* The Secure Mailer license must be distributed with this software. 44 /* AUTHOR(S) 45 /* Wietse Venema 46 /* IBM T.J.
