Mail servers for airpost.net
airpost.net publishes 2 MX records. Senders deliver to the lowest-priority host first, in1-smtp.messagingengine.com, and fall back down the list if it does not answer.
Who runs the mail
The hosts match the pattern of Fastmail. Fastmail hosts the mailboxes and answers the handshake honestly, so an address that does not exist is rejected outright and verdicts are definitive.
What this means for verification
An address at airpost.net passes the free checks (syntax, MX, lists), so the API goes on to the mailbox-level SMTP handshake, which ends before any message is sent. The result is deliverable, risky, or undeliverable with a reason field that names the evidence.
