vip.sina.com MX records
vip.sina.com publishes 4 MX hosts; senders try the lowest priority number first (mx3.vip.sina.com, 5) and fall back to the others in order.
vip.sina.com SPF record
The record on 5 November 2026 was v=spf1 include:spf.sinamail.sina.com.cn -all.
In plain terms, it delegates to spf.sinamail.sina.com.cn. 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.
vip.sina.com DMARC policy
The record is v=DMARC1; p=none;.
p=none only asks for reports; failing mail is delivered as normal.
Can you verify @vip.sina.com addresses?
Our checker treats @vip.sina.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 mx3.vip.sina.com answers for @vip.sina.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.
