Fetch One POP3 Message by Message Number

See more POP3 Examples

Demonstrates the Chilkat MailMan.FetchOne method, which retrieves one message by POP3 message number and stores it in an Email object. The arguments are headerOnly, numBodyLines, the message number (the first message is 1), and the Email. The message remains on the server. This example fetches message 1 in full.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    //  Fetch message number 1 in full.  headerOnly=false (fetch the entire message).
    //  Note: numBodyLines only applies when headersOnly is true (it sets how many lines of the
    //  body to include along with the headers).  When headersOnly is false, the entire message
    //  is fetched and numBodyLines is ignored.

    //  Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
    //  connects and authenticates -- using the property settings above -- whenever a server
    //  operation requires it.  Calling the explicit connect/authenticate methods can still be
    //  helpful to determine whether a failure occurs while connecting or while authenticating.
