No. The reference deployment is a receive-only shared mailbox system. It intentionally does not provide IMAP, POP3, user SMTP submission, calendars or outbound campaigns.
Yes. Administrators assign mailbox memberships, and message access is filtered by those memberships.
One configurable mail domain is supported per reference installation. Multi-domain operation is not qualified in this release.
The automated installer supports clean Ubuntu Server 24.04 LTS only. Other platforms require a reviewed manual port and full acceptance testing.
Hosted mailboxes are receive-only. The isolated public contact service can submit a fixed notification through local Postfix.
No official container deployment is included in this release because SMTP, LMTP, Maildir ownership, systemd and TLS integration require a separately audited design.
It is a release candidate. Automated gates pass, but clean-VPS and external-mail acceptance remain mandatory before stable promotion.
