arizona.gov - Email Domain Verification & Deliverability Report

The domain arizona.gov is the official digital portal for the State of Arizona, providing access to state government services, agencies, and public information. Arizona's state government, headquartered in Phoenix, administers services covering public safety, transportation, health, education, and natural resources across the state.

Arizona.gov implements email authentication protocols including SPF, DKIM, and DMARC to secure official state communications. Following federal guidance under CISA BOD 18-01, government domains at all levels have increasingly adopted strict DMARC policies. Phishing attacks impersonating Arizona state agencies can target residents seeking government services, making authentication essential.

Arizona state government mail servers generally do not operate in catch-all mode. The SMTP infrastructure validates recipient addresses and rejects messages to nonexistent mailboxes. Greylisting and rate limiting are standard practices to control inbound traffic and filter unauthorized senders.

Email deliverability to arizona.gov requires complete authentication compliance. The state's email gateway infrastructure employs multi-layered spam filtering, content analysis, and sender reputation scoring. Senders should verify their SPF and DKIM configurations, publish a DMARC policy, and maintain a positive sending reputation for reliable delivery to Arizona government addresses.
