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.
