14 /* DESCRIPTION
15 /* This module predefines the following addresses:
16 /* .IP MAIL_ADDR_POSTMASTER
17 /* The postmaster handle. 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.
