maktoob.com MX records
maktoob.com publishes a single MX host, mx-mail.maktoob.ukl.yahoo.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.
maktoob.com SPF record
The record on 5 November 2026 was v=spf1 a ip4:77.238.185.168 ip4:77.238.185.167 ip4:217.115.207.224/28 -all.
In plain terms, lists 3 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 hard fail (-all): receivers may reject mail from any server the record does not list.
maktoob.com DMARC policy
The record is v=DMARC1; p=none; pct=100; rua=mailto:[email protected]; ruf=mailto:[email protected];.
p=none only asks for reports; failing mail is delivered as normal.
Aggregate reports go to rua.agari.com, so the domain's owner sees who sends mail as @maktoob.com.
Can you verify @maktoob.com addresses?
Our checker treats @maktoob.com 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 mx-mail.maktoob.ukl.yahoo.net answers for @maktoob.com, 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.
