netcologne.de MX records
netcologne.de publishes 4 MX hosts, all at priority 10, so senders spread mail across them.
netcologne.de SPF record
The record on 5 November 2026 was v=spf1 ip4:89.1.8.0/23 ip6:2001:4dd0:100::/48 ip4:194.8.194.0/24 ip4:81.173.193.0/24 ip4:81.173.194.0/26 ip4:81.173.246.0/24 ip4:185.98.184.0/24 ip4:80.82.206.0/26 ip4:46.228.134.9/32 ip4:62.146.4.26/32 include:spf.pressfile.de ~all.
In plain terms, it delegates to spf.pressfile.de and lists 10 IP ranges directly. 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.
netcologne.de DMARC policy
The record is v=DMARC1; p=none; sp=none; fo=1; adkim=r; aspf=r; ruf=mailto:[email protected]; rua=mailto:[email protected].
p=none only asks for reports; failing mail is delivered as normal.
Aggregate reports go to netcologne.de, so the domain's owner sees who sends mail as @netcologne.de.
Can you verify @netcologne.de addresses?
Our checker treats @netcologne.de 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 cc-mx1.netcologne.de answers for @netcologne.de, 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.
