/contact.ashx · public API

Programmatic contact-form submission. Internally the same code path used by the website’s contact form — useful when embedding the form into another origin via cross-origin POST.

POST `/contact.ashx` #

Submit a contact form. The handler validates the inputs, verifies the captcha first, applies an IP-based rate limit, and drops an RFC 822 .eml file into the IIS SMTP pickup directory for delivery via the configured smart host.

name — 1–120 chars
email — valid RFC 5321-shape
subject — 0–200 chars
message — 1–6000 chars
captcha_token — signed token from /captcha.ashx
captcha_answer — the integer the user typed in

Response

application/json: { "ok": true } on success.

Errors

400 — missing field / field too long / invalid email / captcha failed
405 — non-POST
429 — 5 messages per IP per hour
500 — pickup directory misconfigured or unwritable
