Set Uncommon Email Options

Demonstrates the Chilkat Email.UncommonOptions property, a catch-all for uncommon needs. It defaults to the empty string and should typically remain empty. Recognized keywords include NoBccHeader (do not add the Bcc MIME header for BCC addresses — which must be set before calling AddBcc or AddMultipleBcc) and NO_FORMAT_FLOWED (do not automatically add format=flowed to a Content-Type header). This example sets NoBccHeader.

Background: Long-lived libraries accumulate rare, situational tweaks that do not each deserve their own property. Chilkat gathers these into a single keyword-driven UncommonOptions string. NoBccHeader is a good example: normally a Bcc header is generated (and stripped at send time), but certain workflows want it omitted entirely. Only documented keywords have any effect — unrecognized text is ignored — so leave this empty unless a specific compatibility need arises.
