fix: Skip email rate limiting for self-hosted instances ( #13915 )
...
Self-hosted installations were incorrectly hitting the daily email rate
limit of 100, seeded from `installation_config`. Since self-hosted users
control their own infrastructure, email rate limiting should only apply
to Chatwoot Cloud.
Closes #13913

feat: add per-account daily rate limit for outbound emails ( #13411 )
...
Introduce a daily cap on non-channel outbound emails to prevent abuse.
Fixes https://linear.app/chatwoot/issue/CW-6418/ses-incident-jan-28
## Type of change
- [x] New feature (non-breaking change which adds functionality)
- [x] Breaking change (fix or feature that would cause existing
functionality not to work as expected)
## Summary
- Adds a Redis-based daily counter to rate limit outbound emails per
account, preventing email abuse
- Covers continuity emails (WebWidget/API), conversation transcripts,
and agent notifications
- Email channel replies are excluded (paid feature, not abusable)
- Adds account suspension check in `ConversationReplyMailer` to block
already-queued emails for suspended accounts
## Limit Resolution Hierarchy
1. Per-account override (`account.limits['emails']`) — SuperAdmin
configurable
2. Enterprise plan-based (`ACCOUNT_EMAILS_PLAN_LIMITS`
InstallationConfig)
3. Global default (`ACCOUNT_EMAILS_LIMIT` InstallationConfig, default:
100)
4. Fallback (`ChatwootApp.max_limit` — effectively unlimited)
## Enforcement Points
