This is my mail server project.
I know you're going to tell me yet another open source mail server distribution... your right !
I searched another mail server distribution... and i've tested some like mailcow...mailu...iredmail...mail-in-a-box...kopano... openxchange... But not reponds to my need... principaly to work in full container without adherence to the host... to be abel to work fluently also on kubernetes...
Features roadmap :
- All in container (container engine agnostique, all rootless, no special cap needed, no host dependence)
- SSO Evrywhere : OpenIdc/xoauth2
- MFA where possible
- All user stored in database (mysql or postgresql, i've not chosent for the moment) for dovecot/postfix/sogo/rspamd
- IMAP
- Webmail
- Sieve filter
- Active Sync for the mobile sync
- MTA for all mail traffic and routing
- Dkim, SPF and DMarc support
- SSO with the IDP that support sql database user storage
- fail2ban at reverse proxy level (haproxy/nginx/envoy i've not chosen for the moment, but not iptable that are outside of the container)
- Admin Web tool to manage the user in the database (and protected with OpenIdc too)
- Antispam support
- Mail statistics and Dmarc report dashboard
- Regulards Check/alarms : mx, dkim, spf, dmarc per domain.
- Client autoconfiguration support for auto-discovery protocoles (mozilla autoconfig, microsoft autodiscover, apple mobileconfig)
