Fixed two critical issues with email notifications:
1. Test email API now returns errors properly instead of always showing success
2. Added timeouts to SMTP connections to prevent hanging (10s dial, 30s overall)
The root cause of users not receiving emails was that errors were being
silently logged instead of returned to the API, making it appear successful
when it wasn't. SMTP connections could also hang indefinitely on unreachable
servers.
Note: API uses "server" and "port" JSON fields, not "smtpHost"/"smtpPort"
Frontend fixes:
- Fixed VM thresholds incorrectly showing as 'CT' in alerts UI (issue #295)
- Fixed threshold slider not reaching 0% and 100% edges (issue #295)
- Fixed PBS form auto-filling with PVE settings (issue #296)
- Fixed email config property mapping (server/port instead of smtpHost/smtpPort)
Backend fixes:
- Updated EmailConfig struct to use 'server' and 'port' JSON tags for consistency
- Added 'provider' and 'startTLS' fields to EmailConfig
- Fixed PORT env var to correctly set FrontendPort instead of BackendPort
- Changed default log level from Debug to Info
All changes tested and verified working correctly.
- extend webhook template support to all services (slack, teams, pagerduty)
- properly detect service type and apply correct template
- add pagerduty routing_key support from headers
- fallback to generic json only when no template exists
- handle both individual and grouped alerts for all services
- add proper telegram bot api support with chat_id and text fields
- fix frontend pbs red dot display (was checking 'error' instead of 'unhealthy')
- fix qemu guest agent memory reporting (fallback to mem when freemem is 0)
- extract chat_id from telegram webhook urls when present
- Fixed incorrect RAM usage display for VMs without guest agent (issue #280)
- VMs without guest agent now show 0% usage instead of 100%
- Only show actual usage when guest agent provides FreeMem data
- Containers continue to show accurate usage as before
- Fixed webhook test functionality (issue #279)
- Added proper webhook ID handling in test notification endpoint
- Created SendTestWebhook method to test specific webhooks
- Frontend can now successfully trigger webhook tests
- PBS instances now show as online when datastores are accessible even if version endpoint fails
- Email sending now uses proper STARTTLS support for compatibility with providers like SMTP2GO
- Email recipient input no longer filters entries while typing
- Auto-update setting now properly persists and loads from config
- Fixed CPU usage alerts for offline VMs (already addressed in previous commits)
- Added service field to WebhookConfig to identify Discord webhooks
- Use Discord-specific template when sending Discord webhooks
- Fixed backup type detection for PBS backups (vm/ct)
- Fixed shared storage duplicate IDs across instances
- Fixed alert acknowledge/clear response format to match frontend expectations
- Backend now uses From address as recipient when To array is empty
- Fixed sendEmail and sendGroupedEmail to not check for recipients
- Added detailed logging for SMTP operations
- Fixed recipient logging to show actual recipients sent
This allows users to send test emails to themselves without
having to enter their email address in the recipients field,
as promised by the UI.
