How this service works
Is the domain's email hosted by symantec messagelabs? Looks up the MX records (Cloudflare DoH) and matches them against symantec-messagelabs's mail-exchanger patterns, returning yes/no, the MX hosts and which matched. Provider detection for deliverability, sales and migration work. $0.01 per lookup.
Output
Returns a yes/no answer indicating whether the domain's email is hosted by Symantec MessageLabs, along with the full list of MX hosts discovered via Cloudflare DNS-over-HTTPS and which of those hosts matched against known MessageLabs mail-exchanger patterns.
Example use cases
Sales prospecting email stack detection
“Before I reach out to techfirm.io, can you check whether their email is running through Symantec MessageLabs? I want to know what security stack they're on.”
Pre-migration current provider verification
“We're about to migrate globalpartners.com away from MessageLabs — can you confirm their email is actually hosted there right now by checking their MX records?”
Competitive intelligence email provider audit
“I'm building a list of companies in my market that use Symantec MessageLabs for email — can you check whether innovate-solutions.com is one of them?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/symantec-messagelabs?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically determine whether a single domain's email is routed through Symantec MessageLabs (now part of Broadcom). It is ideal for sales intelligence workflows, pre-migration audits, or competitive research where MessageLabs provider detection is the specific goal. Use sibling bulk endpoints if checking multiple domains at once. Prefer this over generic MX lookup tools when you need pattern-matched provider detection rather than raw DNS data.
Side effects
- Domain has no MX records — returns no match with empty MX host list
- Invalid or non-existent domain name — DNS lookup fails with error
- Cloudflare DoH unavailable — lookup fails due to upstream DNS error
- Domain uses MessageLabs-adjacent but unrecognized patterns — may return false negative
