Fetch a POP3 Message's Raw MIME by UIDL

Demonstrates the Chilkat MailMan.FetchMimeBd method, which fetches an email from the POP3 server by UIDL and stores the raw MIME source bytes in a BinData. Chilkat clears the BinData before downloading. This example fetches one message's MIME into a BinData.

Background: Sometimes you want the message exactly as it arrived — the raw MIME bytes — rather than a parsed Email object, for example to archive it verbatim as a .eml file, forward it untouched, or hash it. Fetching into a BinData preserves every byte precisely, without any parsing or re-encoding that could alter the original.

//  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.
