(SQL Server) IMAP Download All Email One at a TimeDemonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) Note: This example requires Chilkat v11.0.0 or greater.
-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls. -- CREATE PROCEDURE ChilkatSample AS BEGIN DECLARE @hr int -- Important: Do not use nvarchar(max).
