41  =head1 DESCRIPTION  =head1 DESCRIPTION
42    
43  Core module for notice sender's functionality.  Notice sender is mail handler. It is not MTA, since it doesn't know how to
44    receive e-mails or send them directly to other hosts. It is not mail list
45    manager because it requires programming to add list members and send
46    messages. You can think of it as mechanisam for off-loading your e-mail
47    sending to remote server using SOAP service.
48    
49    It's concept is based around B<lists>. Each list can have zero or more
50    B<members>. Each list can have zero or more B<messages>.
51    
52    Here comes a twist: each outgoing message will have unique e-mail generated,
53    so Notice Sender will be able to link received replies (or bounces) with
54    outgoing messages.
55    
56    It doesn't do much more than that. It B<can't> create MIME encoded e-mail,
57    send attachments, handle 8-bit characters in headers (which have to be
58    encoded) or anything else.
59    
60    It will just queue your e-mail message to particular list (sending it to
61    possibly remote Notice Sender SOAP server just once), send it out at
62    reasonable rate (so that it doesn't flood your e-mail infrastructure) and
63    track replies.
64    
65    It is best used to send smaller number of messages to more-or-less fixed
66    list of recipients while allowing individual responses to be examined.
67    Tipical use include replacing php e-mail sending code with SOAP call to
68    Notice Sender. It does support additional C<ext_id> field for each member
69    which can be used to track some unique identifier from remote system for
70    particular user.
71    
72    It comes with command-line utility C<sender.pl> which can be used to perform
73    all available operation from scripts (see C<perldoc sender.pl>).
74    This command is also useful for debugging while writing client SOAP
75    application.
