portugalmail.pt email servers, SPF and DMARC

portugalmail.pt publishes 3 MX hosts; senders try the lowest priority number first (a.mx.portugalmail.pt, 10) and fall back to the others in order.

The record on 5 November 2026 was v=spf1 a mx include:_spfi.smail.eu -all.

In plain terms, it delegates to _spfi.smail.eu. The top level uses 3 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.

The record is v=DMARC1; p=reject; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1:d:s.

p=reject asks receivers to refuse mail that fails DMARC.

Aggregate reports go to sooma.com, so the domain's owner sees who sends mail as @portugalmail.pt.

What that means for you: if a contact gives an @portugalmail.pt address and you send to them, nothing changes. But never put an @portugalmail.pt address in the From line of mail sent through your own tool or ESP. It can't pass DMARC for portugalmail.pt, and this policy tells receivers to refuse it.

Our checker treats @portugalmail.pt 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 a.mx.portugalmail.pt answers for @portugalmail.pt, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.

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.
