Can you verify @bluemail.ch addresses?
Our checker treats @bluemail.ch 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 @bluemail.ch itself, but its mail goes to the same servers as bluewin.ch, so expect @bluemail.ch 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.
