aol.de MX records
aol.de publishes a single MX host, mx-aol.mail.gm0.yahoodns.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.
37 other domains we checked on the same day also hand their mail to Yahoo Mail servers, with different records from aol.de: ameritech.net, aol.at, flash.net, myyahoo.com, nvbell.net, pacbell.net, prodigy.net, snet.net and 29 more.
aol.de SPF record
The record on 5 November 2026 was v=spf1 redirect=_spf.mail.yahoo.com.
In plain terms, it delegates to _spf.mail.yahoo.com. The top level uses 1 DNS-querying term; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
aol.de DMARC policy
The record is v=DMARC1; p=reject; pct=100; rua=mailto:[email protected]; ruf=mailto:[email protected];.
p=reject asks receivers to refuse mail that fails DMARC.
Aggregate reports go to rua.agari.com, so the domain's owner sees who sends mail as @aol.de.
What that means for you: if a contact gives an @aol.de address and you send to them, nothing changes. But never put an @aol.de address in the From line of mail sent through your own tool or ESP. It can't pass DMARC for aol.de, and this policy tells receivers to refuse it.

Can you verify @aol.de addresses?
Our checker treats @aol.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 tested @aol.de itself, but its mail goes to the same servers as aol.com, so expect @aol.de results to follow the pattern described there. 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.
What Yahoo Mail documents for senders
- Yahoo asks every sender to authenticate with SPF and DKIM, and bulk senders to publish DMARC, offer one-click unsubscribe and keep spam complaints low. Yahoo Sender Hub: best practices
- Yahoo publishes the meaning of its own SMTP replies, including the deferrals it uses to slow unfamiliar senders. Yahoo Sender Hub: SMTP error codes
