midco.net MX records
midco.net publishes 2 MX hosts, all at priority 10, so senders spread mail across them.
5 other domains we checked on the same day also route mail to hosts under cloudfilter.net, with different records from midco.net: brighthouse.com, eircom.net, mchsi.com, mediacombb.net and bresnan.net.
midco.net SPF record
The record on 5 November 2026 was v=spf1 +include:_spf.midco.net ~all.
In plain terms, it delegates to _spf.midco.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.
midco.net DMARC policy
The record is v=DMARC1; p=quarantine; pct=10; rua=mailto:[email protected].
p=quarantine asks receivers to send failing mail to spam, applied to 10% of failing mail.
Aggregate reports go to midco.net, so the domain's owner sees who sends mail as @midco.net.
What that means for you: if a contact gives an @midco.net address and you send to them, nothing changes. But never put an @midco.net address in the From line of mail sent through your own tool or ESP. It can't pass DMARC for midco.net, and this policy tells receivers to junk it.
midco.net TLS policy
_mta-sts.midco.net publishes v=STSv1; id=07162025a;, so midco.net uses MTA-STS: sending servers that support it must deliver over verified TLS or not at all (RFC 8461).
It also asks for TLS reports with v=TLSRPTv1; rua=mailto:[email protected] (RFC 8460).
Can you verify @midco.net addresses?
Our checker treats @midco.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 mdc-east.mx.a.cloudfilter.net answers for @midco.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.
