sonic.net MX records
sonic.net publishes 2 MX hosts, all at priority 10, so senders spread mail across them.
sonic.net SPF record
The record on 5 November 2026 was v=spf1 include:mail.sonic.net ~all.
In plain terms, it delegates to mail.sonic.net. The top level uses 1 DNS-querying term; 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.
sonic.net DMARC policy
The record is v=DMARC1; p=none; rua=mailto:[email protected];.
p=none only asks for reports; failing mail is delivered as normal.
Aggregate reports go to ag.us.dmarcian.com, so the domain's owner sees who sends mail as @sonic.net.
sonic.net TLS policy
It also asks for TLS reports with v=TLSRPTv1; rua=mailto:[email protected] (RFC 8460).
Can you verify @sonic.net addresses?
Our checker treats @sonic.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 mailin-01.mx.sonic.net answers for @sonic.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.
