TLS-RPT
Reports about TLS delivery failures between mail servers.
SMTP TLS Reporting lets domains receive aggregate reports when senders fail to deliver mail over TLS. It is commonly paired with MTA-STS so domain owners can see whether strict transport policies are causing failures.

An agent stack treats email as a two-way primitive. Inbound has to arrive as structured JSON a tool call can consume, sends have to be safe to retry when a model loop repeats itself, and every action needs an audit trail. A provider without inbound parsing only solves half the problem.
Applied to tls-rpt, that means weighing inbound parsing, idempotency keys, webhook coverage, and operating track record ahead of the rest, against inbound parsing into tool calls and model-generated sends that must not duplicate.
