Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
docker-mailserver
- No admin web UI — all config is via files and the CLI
- No bundled webmail or groupware (calendar/contacts)
- Deliverability, DNS, and TLS setup are entirely your responsibility
- Not a newsletter/marketing tool — mailboxes only
Forward Email
- Self-hosting is complex and far less documented than the hosted service
- Newsletter/campaign tooling is thin compared to Mailchimp
- BUSL-1.1 license is source-available, not fully OSI-open
- Running production email requires significant infra and DNS expertise
