How this service works
POP3 service discovery (_pop3._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's pop3 service lives without guessing hosts. $0.01 per lookup.
Output
Returns the SRV record details for _pop3._tcp.<domain> including priority (integer for server selection ordering), weight (load-balancing factor), port number (where POP3 listens), and target hostname, sourced from Cloudflare DNS over HTTPS. If no SRV record exists, returns an empty or error response.
Example use cases
Email client auto-configuration
“What host and port should my email client connect to for POP3 access on fastmail.com? Look up their _pop3._tcp SRV record.”
Mail infrastructure audit
“I'm auditing the mail setup for acmecorp.com — can you pull the POP3 SRV record so I can see what server and port they've configured for POP3?”
Validate POP3 service before migration
“Before I migrate our users, can you check the _pop3._tcp SRV record for oldmailhost.org to confirm the target host and port are still pointing to the right place?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/pop3-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover a domain's POP3 service configuration via DNS SRV records rather than guessing hostnames like 'pop.domain.com' or 'mail.domain.com'. Ideal for email client auto-configuration, infrastructure auditing, or verifying POP3 service endpoints before connecting. Prefer this over generic DNS tools when you specifically need SRV record fields (priority, weight, port, target) for the POP3 protocol.
Side effects
- Domain has no _pop3._tcp SRV record — returns empty result or NXDOMAIN
- Invalid or malformed domain name input — returns error
- Cloudflare DoH upstream timeout — returns service unavailable
- Domain exists but POP3 SRV record not published — lookup returns no results
- Network failure reaching Cloudflare DoH resolver
