Mail servers for barracudanetworks.com

barracudanetworks.com publishes 2 MX records. Senders deliver to the lowest-priority host first, d160223a.ess.barracudanetworks.com, and fall back down the list if it does not answer.

Who runs the mail

The hosts match the pattern of Barracuda. A Barracuda gateway receives the mail first. Like other gateways it tends to accept every recipient during the handshake, so mailbox existence usually cannot be confirmed from outside.

What this means for verification

An address at barracudanetworks.com 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.
