mail.langmail.me. This page is the endpoint map — the same one an export tool or a competitor’s migration script would use. That’s the point.
Endpoints
Autodiscovery
Standard clients fill in these endpoints from just a@langmail.me address — no manual server entry. Three mechanisms (DNS SRV, Mozilla autoconfig, MS Autodiscover) cover the common desktop clients, all pointing back at mail.langmail.me:
The
_pop3/_pop3s SRV sentinels steer SRV-based clients (macOS Mail) to IMAP rather than POP. Autodiscovery carries settings only — you still generate and enter an app password.
Both chains also reach the apex (langmail.me), at different points: Autodiscover probes it before autodiscover.langmail.me, while autoconfig falls back to langmail.me/.well-known/autoconfig/ only if autoconfig.langmail.me fails. The apex is the marketing site, so it answers 404 on both paths rather than serving its SPA fallback — an HTML page returned with 200 reads as a valid response and can strand a client mid-chain.
Two clients cannot be set up this way. iPhone and iPad Mail resolve setup against Apple’s private built-in provider database: they do not query SRV, do not fetch Mozilla autoconfig, and discard Autodiscover for plain IMAP accounts (that path is Exchange/EAS only). iOS is configured instead with a downloadable configuration profile, which — unlike the mechanisms above — carries the credential as well as the settings. Recent Outlook releases, including Outlook for iOS, also fail to apply Autodiscover for IMAP accounts and need manual server entry. The records above are correct and serve macOS Mail, Thunderbird, and other standards-consuming clients.
Authentication
Your account password is never used directly by mail protocols — interactive sign-in happens in the browser, and each device or script gets its own revocable app password.
What this buys you
- Complete export, any time. An IMAP or JMAP sync of your mailbox is a complete, portable archive in standard formats — including the classification keywords Langmail adds, which are plain mailbox keywords.
- Client freedom. Apple Mail, Thunderbird, Outlook, mutt, offlineimap — any standards-compliant mail client works without Langmail’s involvement.
- No proprietary surface to depend on. The MCP server itself is a thin layer over JMAP and CalDAV. If you outgrow it, the protocols underneath are yours.
Metadata that lives outside the mailbox — account settings, Morning Brief configuration — is app-level and not part of the protocol surface.
