## Summary
- Add email forwarding as a new message channel type, allowing users to
forward emails from addresses like `support@mycompany.com` into Twenty
- Inbound emails arrive via S3 (SES → S3 bucket), are polled by a cron
job, parsed, routed to the correct workspace/channel, and persisted as
messages
- Dedicated settings page at `/settings/accounts/new-email-forwarding`
where users provide their source email handle and receive a unique
forwarding address
- Forwarding channels bypass the IMAP/mailbox sync state machine — they
skip cron-driven sync, relaunch, and message-list-fetch lifecycle stages
- Forwarding address section shown at the top of the Emails settings
page so users can find/copy their addresses after initial setup
- Tab names for forwarding channels display the user-provided handle
(e.g. `support@mycompany.com`) instead of the internal routing address
- Shared utilities extracted from IMAP driver: `extractThreadId`,
`extractParticipants`, `extractAddresses` to avoid code duplication
- Uses the existing S3 bucket (STORAGE_S3_*) with `inbound-email/`
prefix — no separate bucket needed
- Feature gated behind `isEmailForwardingEnabled` client config
(requires `INBOUND_EMAIL_DOMAIN` + S3 storage)
## New backend modules
- `InboundEmailS3ClientProvider` — lazy-initialized S3 client using
existing storage config
- `InboundEmailStorageService` — S3 operations (get, move to
processed/unmatched/failed)
- `InboundEmailParserService` — RFC 822 parsing via `postal-mime`,
builds `MessageWithParticipants`
- `InboundEmailImportService` — orchestrates download → parse → route →
persist → archive
- `MessagingInboundEmailPollCronJob` — polls S3 `incoming/` prefix,
enqueues import jobs
- `CreateEmailForwardingChannelInput` DTO — accepts user-provided
`handle`
## New frontend components
- `SettingsAccountsNewEmailForwardingChannel` — dedicated page with
handle input form + forwarding address result
- `SettingsAccountsEmailForwardingSection` — forwarding address list on
the Emails settings page
- `useConnectedAccountHandleMap` — shared hook for account ID → handle
lookup
- `useCreateEmailForwardingChannel` — mutation hook accepting handle
parameter
## Test plan
- [x] 17 unit tests for inbound email import service (all outcomes:
imported, unmatched, loop_dropped, unconfigured, parse_failed,
persist_failed)
- [x] 16 tests for `computeSyncStatus` including EMAIL_FORWARDING cases
- [x] 11 tests for `extractEnvelopeRecipient` utility
- [x] TypeScript typechecks pass for both twenty-server and twenty-front
- [x] Lint passes for both packages
- [ ] Manual: create forwarding channel, verify forwarding address
generated
- [ ] Manual: send email to forwarding address, verify it appears in
Twenty
