Yes. You can verify any @Yahoo.co.uk address in real time with a direct SMTP handshake that provides 99.7% accuracy. Yahoo.co.uk is operated by Yahoo Inc., runs 1 mail server, enforces 2 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
yahoo.co.uk publishes 1 MX record. The primary mail exchanger is mx-eu.mail.am0.yahoodns.net, hosted by Yahoo Mail, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | mx-eu.mail.am0.yahoodns.net | 188.125.72.73 | Reachable |

A live SMTP handshake connects to Yahoo.co.uk's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
