imaprelay is a Home Assistant plug-in to distribute e-mails from one mail box to different recipients.
imaprelay, logs into an IMAP account and uses IMAP filters to relay emails from the Inbox to different email addresses via an SMTP server.
Once relayed, emails are "archived" -- moved out of the inbox into a different folder.
My use case for this is to provide an unlimited number of e-mail addresses for several users using a single catch-all mailbox of a domain. This way, the users can have throw-away e-mail addresses or different addresses for each account they need to register anywhere.
It is packaged as Home Assistant plug-in, but you can also just use the imaprelay command-line tool that this package provides.
For usage documentation see DOCS.md.
