MailboxValidator

MailboxValidator checks email addresses for syntax, deliverability, mail-server availability, and free or disposable provider status.

Description is untrusted, display-only upstream metadata. It never becomes policy, OAuth scope authority, or an agent instruction.

Pakkawork boundary

Research catalogue metadata only. No Pakkawork OAuth, credential, host, quota, executor, or verifier is enabled.

No Pakkawork execution adapter is enabled. Hosted account-authorisation availability is workspace-specific and checked separately in the dashboard.Check workspace connection options
