POP3

Legacy POP3 inbox ingestion. Saves messages as .eml files plus a _Message node. Use only when IMAP is not available — POP3 has no folder concept and limited delta semantics.

What gets ingested

Element	Mapped to
Inbox messages	_Message + _FileEntry (the raw .eml) + _Blob
Attachments	Extracted from the .eml into _FileEntry + _Blob

No folder hierarchy — POP3 protocol has only a flat inbox.

Authentication

• Type: Username + password.

Access control mapping

• Inherits the PermissionsSetting (users + access groups) from the integration form.

Sync cadence

• Runs on demand / cron (the workspace orchestrates the schedule).
• Incremental sync: tracks LastRetrievedMessageIndex. POP3 has no UIDVALIDITY equivalent so the connector relies on UIDL where the server supports it.

Notable

• Most modern mailboxes also expose IMAP; prefer that connector if you have a choice.
