Created custom Dockerfile for Netdata container that includes msmtp
and msmtp-mta packages for sending email notifications.
Changes:
- Added netdata/Dockerfile extending netdata/netdata:latest
- Installed msmtp, msmtp-mta, and ca-certificates via apk
- Set proper permissions (600) for msmtprc config file
- Updated compose.yaml to build from custom Dockerfile
This enables Netdata to send health alarm notifications via email
using the IONOS SMTP configuration in msmtprc.
