(While conventional e-mail -has some reciept support, it's sporadic, e-mail client-specific, and -generally the receiver can opt to not send one, making it useless in -this case.) - -=item * B: LON-CAPA knows about the sender, such as where -they are in a course. When a student mails an instructor asking for -help on the problem, the instructor receives not just the student's -question, but all submissions the student has made up to that point, -the user's rendering of the problem, and the complete view the student -saw of the resource, including discussion up to that point. Finally, -the instructor is reading all of this inside of LON-CAPA, not their -email program, so they have full access to LON-CAPA's grading -interface, or other features they may wish to use in response to the -student's query. - -=back - -Users can ask LON-CAPA to forward messages to conventional e-mail -addresses on their B screen, but generally, LON-CAPA messages -are much more useful then traditional email can be made to be, even -with HTML support. +lonmsg provides routines for sending messages. Right now, this document will cover just how to send a message, since it is likely you will not need to programmatically read messages, since lonmsg already implements that functionality. +The routines used to package messages and unpackage messages are not +only used by lonmsg when creating/extracting messages for LON-CAPA's +internal messaging system, but also by lonnotify.pm which is available +for use by Domain Coordinators to broadcast standard e-mail to specified +users in their domain. The XML packaging used in the two cases is very +similar.
