MafiaSMTP

The shared sending layer the rest of the line sends through: 13 mail providers, encrypted credential storage, routing and fallback.

Features

  • Provider catalog covering 13 mail platforms, with 14 connection choices in the source.
  • Multiple simultaneous connections, each with its own name, provider, from address and default/fallback flags, with credentials stored encrypted and never returned by the administrator or the API.
  • Per-sender routing rules that match an exact From address first, then a From domain, with priority ordering inside each rule type.
  • One fallback attempt to a second connection after a proven non-delivery, and no automatic retry on an uncertain outcome.
  • A searchable email log covering every send attempt, with status filtering and explicit resend from the administrator or the API, plus a guard that refuses to resend an uncertain record.
  • Test send, failure alerts and a simulation mode that contacts no transport and is marked in the log.
  • OAuth connection flows for Gmail, Microsoft and Zoho, using delegated authorization, one-use state, PKCE and minimum send scopes.
  • A five-route API for status, connections, logs, test send and resend, with recipient addresses masked and credentials, bodies and raw provider responses never served.
  • Live verified sending through Generic SMTP and through Amazon SES in both SMTP and API modes, each with an inbox receipt on the testing install.

Status: shipped. The core product shipped as version 2026.11.8.1 and passed independent acceptance on November 12, 2026, with 529 behavioral checks reproduced again on November 14, 2026. Live sending is verified for Generic SMTP and Amazon SES; live account and OAuth acceptance for the other providers is still open.
