grandecom.net MX records
grandecom.net publishes a single MX host, mxin.mygrande.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.
grandecom.net SPF record
The record on 5 November 2026 was v=spf1 ip4:66.90.130.0/24 ip4:66.90.138.144/28 ip6:2607:e400:1002:0:66:90:130:0/48 ip6:2607:e400:1002:0:66:90:130:130 mx include:_spf.wave.syn-alias.com a:sdm1.quickbooks.net ~all.
In plain terms, it delegates to _spf.wave.syn-alias.com and lists 4 IP ranges directly. 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 soft fail (~all): mail from unlisted servers should be accepted but treated as suspicious.
grandecom.net DMARC policy
_dmarc.grandecom.net returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @grandecom.net easier to spoof (RFC 7489).
Can you verify @grandecom.net addresses?
Our checker treats @grandecom.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 mxin.mygrande.net answers for @grandecom.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.
