(SQL Server) POP3 using HTTP Proxy

Demonstrates how to communicate with a POP3 server through an HTTP proxy.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

CREATE PROCEDURE ChilkatSample

    DECLARE @hr int
    DECLARE @iTmp0 int

    -- This example assumes the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    -- The mailman object is used for receiving (POP3) 
    -- and sending (SMTP) email.

    -- To connect through an HTTP proxy, set the HttpProxyHostname
    -- and HttpProxyPort properties to the hostname (or IP address)
    -- and port of the HTTP proxy.  Typical port numbers used by
    -- HTTP proxy servers are 3128 and 8080.

    -- traffic to pass.  Otherwise this does not work.

    -- will automatically connect and authenticate (i.e. login)
    -- if not already connected.  The connection will remain
    -- open after the method call returns so that subsequent
    -- calls do not need to re-establish the connection.

    -- proxy.
