caiway.nl MX records
caiway.nl publishes 4 MX hosts; senders try the lowest priority number first (mx1.caiway.net, 10) and fall back to the others in order.
caiway.nl SPF record
The record on 5 November 2026 was v=spf1 include:_spf.dfn.nl include:_senderspf.copernica.com include:spf.mandrillapp.com include:_spf.mailplus.nl include:_spf.megamail.nl include:servers.mcsv.net include:mailgun.org -all.
In plain terms, it delegates to _spf.dfn.nl, _senderspf.copernica.com, spf.mandrillapp.com, _spf.mailplus.nl, _spf.megamail.nl, servers.mcsv.net and mailgun.org. The top level uses 7 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.
caiway.nl DMARC policy
The record is v=DMARC1; p=none.
p=none only asks for reports; failing mail is delivered as normal.
Can you verify @caiway.nl addresses?
Our checker treats @caiway.nl 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 mx1.caiway.net answers for @caiway.nl, 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.
