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