VERDICT

Should I use Zextras Community – Carbonio Community Edition?

Private e-mail server for free. Prevent spoofing, phishing, and spam on your servers. - community.zextras.com

Depends. A free, self-hosted email server that only makes sense if you have Linux admins and a real data-sovereignty reason; for anyone else it's operational overkill. Evidence is thin (3 public sources, no independent reviews), so treat this as directional.

Confidence

Low. Based on 3 public sources; no independent reviews or user quotes found, so confidence is low.

Gotchas - check before you buy

high

Self-hosting means you own patching, backups, and spam/deliverability firefighting; help is community-driven.

medium

Install guides target Ubuntu 20.04 LTS specifically; OS upgrades may force migrations.

medium

Mail servers are constant attack targets; even backscatter protection is yours to configure.

low

Paid/commercial tiers aren't shown on this community site; verify what's actually free long-term.
