How this service works
MX, SPF and DMARC check / Проверка почтовой защиты домена
Output
Returns a JSON object with the domain name, arrays of MX, SPF, and DMARC DNS record values, and boolean flags (есть_mx, есть_spf, есть_dmarc) indicating whether each record type is present for the queried domain.
Example use cases
Audit vendor domain email security
“Before we start emailing from our new vendor partnership domain, can you check whether sendgrid.com has valid MX, SPF, and DMARC records set up?”
Investigate suspicious sender domain
“I got an email from someone claiming to be from acmecorp.biz — can you check if that domain actually has proper email authentication like SPF and DMARC configured?”
Pre-send domain deliverability check
“We're about to launch an email campaign from newsletters.mybrand.com — can you verify it has MX, SPF, and DMARC records in place so our emails don't get rejected?”
Technical details
Endpoint
GEThttps://it.finlandfoxvpn.shop/api/v1/domain/mail-securityWhen to prefer
Use this endpoint when you need a quick, combined lookup of all three major email security DNS record types (MX, SPF, DMARC) in a single call. It is ideal for bulk domain auditing, pre-send deliverability checks, or security assessments where you want a concise pass/fail flag alongside the raw record data. Prefer it over generic DNS lookup endpoints when the specific goal is email security validation rather than general DNS inspection.
Side effects
- Domain does not exist — returns empty arrays and all boolean flags as false
- DNS timeout — may return empty results without distinguishing from a genuinely unconfigured domain
- Invalid domain format in query parameter — may return error or empty response
- Domain has no email configuration at all — valid response but all flags false and all arrays empty
