IMAP probe

The IMAP probe sends a sequence of IMAP commands to a mail server. Like the SMTP probe, each command is configured individually and the server’s tagged and untagged responses are recorded.

Set an expected response tag on any command. If the server returns a different result, the history entry is marked as failed.

{{variable}} placeholders are supported in the host field and in each command’s data field.

The history panel shows untagged server lines for each command exchange. Commands are matched to history entries by their command string.
