Fetch a Range of POP3 Messages

See more POP3 Examples

Demonstrates the Chilkat MailMan.FetchRange method, which retrieves a range of messages from the POP3 mailbox and appends them to an EmailBundle. The arguments are keepOnServer, headersOnly, numBodyLines, a zero-based inclusive startIndex and endIndex, and the EmailBundle. This example fetches the first five messages.

    //  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.
