Email send test

Test whether a mail server or a sending API can actually deliver a message — watch the live SMTP conversation or API request/response as it happens, ending in a clear success or failure.

We do not retain any of the details you provide to this form. Naturally all security conscious guys will read that statement with a critical eye, but we can assure you that Spoofhound doesn't retain any details.
Test type

Port 25 cannot be tested here — Cloudflare blocks outbound port 25 platform-wide to prevent spam relay abuse. Use 587 (STARTTLS) or 465 (implicit TLS/SSL) instead.
