This manual is primarily concerned with 3 “types” of email:
emails sent by the underlying system
emails sent via Python logging mechanism
emails sent explicitly by a Poser/Rattail app
The first, “emails sent by the underlying system” refers primarily to emails
sent by the
cron daemon. See System Emails for more about those.
The second, “emails sent via Python logging mechanism” is covered in Logging to Email.
The third, “emails sent explicitly by a Poser/Rattail app” is the primary motivation behind this section of the manual. In particular see the sections about Rattail Configuration, Customizing Templates and Programmatically Sending Email.
Finally, if you’re sending email to the public, it may be helpful to detect bounces and e.g. flag an address as invalid if it triggers a bounce. See Handling Email Bounces for more on that.
