online.ua email servers, SPF and DMARC
Mail for @online.ua goes to _dc-mx.ccc8c6dd8f66.online.ua (MX priority 10), as DNS showed on 5 November 2026. The host sits under online.ua. The domain publishes 2 separate SPF records, which RFC 7208 treats as a permanent error and no DMARC record, which decide whether mail claiming to be from @online.ua is trusted.

online.ua MX records
online.ua publishes a single MX host, _dc-mx.ccc8c6dd8f66.online.ua. 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.
online.ua SPF record
online.ua publishes 2 SPF records: v=spf1 a mx ip4:91.194.250.152 ~all and v=spf1 mx ip4:77.120.110.128/27 a:dc19-srv101-vm001-router.ideil.net ~all. RFC 7208 §4.5 says a receiver that finds more than one must return a permanent error, so SPF checks for @online.ua mail fail outright at strict receivers.
In plain terms, lists 1 IP range directly. The top level uses 2 DNS-querying terms; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
It ends in a soft fail (~all): mail from unlisted servers should be accepted but treated as suspicious.
online.ua DMARC policy
_dmarc.online.ua returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @online.ua easier to spoof (RFC 7489).
Can you verify @online.ua addresses?
Our checker treats @online.ua 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 _dc-mx.ccc8c6dd8f66.online.ua answers for @online.ua, 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.
