Coldflow's pypesdev#1 deliverability blocker for self-hosted senders is transport-layer misconfiguration (TLS, AUTH, DNSBL, reverse DNS). Surface smtp-warmer right under "connect google smtp accounts" so users hit it the moment they wonder "why is my mail landing in spam?". One npx command, zero deps, no API keys. Mirrors the dmarc-doctor sub-bullet pattern under the SPF/DKIM/DMARC line. Co-Authored-By: Paperclip <noreply@paperclip.ing>
