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.
Background: Fetching a range instead of everything is useful for paging through a large mailbox, or resuming after an interruption — download messages 0–99, then 100–199, and so on. Combined with
headersOnly, it lets you build a quick message-list view without pulling full bodies and attachments up front.Chilkat Tcl Downloads

# keepOnServer=cktrue, headersOnly=ckfalse (fetch the entire message).
# Note: numBodyLines only applies when headersOnly is 1 (it sets how many lines of the
# body to include along with the headers). When headersOnly is 0, the entire message
# is fetched and numBodyLines is ignored.
