Configure email Transports

Use IMAP or POP3 to receive mail content and SMTP/email to send Flow output. Test with a dedicated non-production mailbox and approved recipients.

Scope​

TransportMain controls
IMAP inboundHost, Port, User Name, Password, SSL Settings, Mailbox, authentication/OAuth values, optional address filters, After Receiving, move folder and optional custom processing script
POP3 inboundPOP Host, POP Port, username/password, SSL, authentication/OAuth values and SASL choice
SMTP outboundTo Email, CC, BCC, Subject, plain/HTML body, attachment-as-body choices and read-receipt request

SMTP delivery uses the configured Velox email infrastructure as well as the Transport message fields. Confirm sender, relay, TLS/authentication and recipient policy in the target environment.

Controlled setup​

  1. Create the email Transport and leave Active clear.
  2. Configure a dedicated test mailbox or approved test recipients. Store credentials and OAuth client material through approved controls.
  3. For inbound mail, set mailbox/address filters and After Receiving so a message is not repeatedly collected. Test custom processing scripts separately.
  4. For outbound mail, use an unambiguous subject, safe body and sanitised attachment. Do not send customer or production data during initial testing.
  5. Select Test with.... Confirm receipt/collection, attachment content and the post-receipt mailbox state.
  6. Save and link the Transport to a controlled Flow only after independently verifying delivery and duplicate behaviour.

Constraints and failure behaviour​

  • IMAP, POP3 and SMTP server/authentication combinations require deployment-specific compatibility testing.
  • A read receipt is a request, not proof of delivery or reading.
  • A successful SMTP hand-off does not prove final recipient delivery.
  • Clear Mail is destructive; use it only on an approved test mailbox after preserving required evidence.
  • Moving/deleting inbound messages before downstream processing is recoverable can cause data loss.
  • Email addresses, subjects, bodies, attachments and traces may contain sensitive data.
