Gets or sets whether MailBee should save currently downloaded envelopes in LastDownloadedEnvelopes property.
If true, any method of Imap component which receives FETCH responses from the server (like DownloadEnvelopes, DownloadEntireMessages, GetFolderSize, etc) will populate LastDownloadedEnvelopes collection with Envelope objects received and parsed during the method execution; if false, LastDownloadedEnvelopes property will always return a null reference (Nothing in Visual Basic). The default value is false.
