How First Solar receives email (measured 2026-09-05)

Mail sent to firstsolar.com is received by Microsoft 365 (mailbox provider), measured 2026-09-05 in our Inbox Rules Index.

First Solar publishes a DMARC policy of p=none, which only monitors, a soft SPF record (~all), and no MTA-STS policy.

These are First Solar's settings for receiving mail, read from public DNS on 2026-09-05. They say nothing about where your own mail lands. A security gateway or Microsoft 365 in front of the mailbox is one of the setups that most often answer catch-all or unknown to a verifier, so verify each address rather than trusting the format alone.
