"""
|
|
Forward messages sent to the configured email gateway to Zulip.
|
|
|
|
For zulip.com, messages to that address go to the Inbox of emailgateway@zulip.com.
|
|
Zulip voyager configurations will differ.
|
|
|
|
Messages meant for Zulip have a special recipient form of
|
|
|
|
<stream name>+<regenerable stream token>@streams.zulip.com
|
|
|
|
This pattern is configurable via the EMAIL_GATEWAY_PATTERN settings.py
|
|
variable.
|
|
|
|
Run this in a cronjob every N minutes if you have configured Zulip to poll
|
|
an external IMAP mailbox for messages. The script will then connect to
|
|
your IMAP server and batch-process all messages.
|
|
|
|
We extract and validate the target stream from information in the
|
|
recipient address and retrieve, forward, and archive the message.
