Mail and abuse contact

This page is the direct contact point for operational email via our systems (postmaster and abuse) and for urgent cases by phone.

Postmaster

Deliverability, bounces, technical SMTP issues, and postmaster requests.

Report spam, compromise, or security incidents related to our mail.

For urgent operational cases (outage, block, security incident).

SMTP for hosted customer domains and operational senders.
No open relay; outbound filtering, rate limits, and bounce handling.
For postmaster requests: include sender domain, timestamp (UTC), Message-ID, and affected recipients.
For abuse reports: include full headers, a sample message (as .eml), and affected IPs or domains.
Response times depend on severity; security-relevant incidents are prioritized.
