Implementing Node.js SaaS Password Reset: Email Deliverability and Bounce Handling

·1 views

Send password-recovery mail through a verified, dedicated mail identity, and make bounce processing an idempotent state transition that the Node.js application consults before every attempt. TL;DR: SPF, DKIM, and DMARC establish an authentication path; they do not tell your application whether a particular mailbox has failed, so a media SaaS also needs a durable suppression ledger, authenticated event ingestion, and a rollback path that does not silently reopen every bad address. A provider accepting a message is only the start of the transaction. The page worth designing around is recovery_de

When do AI agents actually matter? Benchmarking RAG vs GraphRAG vs Agentic GraphRAG on TigerGraph

No Meta approval, no per-message platform fees, and your convers

Driftnet: one box that catches everything I would otherwise forget

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend I built Driftnet for my friend Samuel. Before I wrote any code I asked him one question: what is actually going wrong for you? Samuel is always busy and always building something, and ideas, links and opportunities reach him from everywhere. He did not give me a feature list. He told me a story.
