Mail servers for proofpoint.com
DNS lists 4 mail hosts for proofpoint.com, starting with mxb-00148501.gslb.pphosted.com. Lower priority values are tried first; the rest exist for failover.
Who runs the mail
The hosts match the pattern of Proofpoint. Proofpoint fronts the domain as a security gateway. Gateways generally accept any recipient and filter afterwards, so a mailbox-level probe rarely gets a definitive no; treat catch-all as the normal state and lean on bounce feedback for accuracy.
What this means for verification
For proofpoint.com, verification runs the whole pipeline: syntax, live MX, the open lists, and then the SMTP handshake with the mail host, with no message ever transmitted. Each verdict carries a machine-readable reason.
