cantv.net MX records
cantv.net publishes a single MX host, relay.cantv.net. With no backup host, a sender that can't reach it queues the message and retries until the server answers or the queue gives up.
cantv.net SPF record
The record on 5 November 2026 was v=spf1 ip4:200.44.32.0/23 ip4:200.11.173.0/24 ip4:161.196.38.0/28 -all.
In plain terms, lists 3 IP ranges directly. The top level uses 0 DNS-querying terms; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
It ends in a hard fail (-all): receivers may reject mail from any server the record does not list.
cantv.net DMARC policy
_dmarc.cantv.net returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @cantv.net easier to spoof (RFC 7489).
Can you verify @cantv.net addresses?
Our checker treats @cantv.net like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not published a test of how relay.cantv.net answers for @cantv.net, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
