//  Once the mailbox is selected, the NumMessages property

    //  Download the email by sequence number.

    //  ... your application may process each MIME string...
  end;

//  An alternative is to download each email in the form of an
//  email object, like this:

for i := 1 to n do
  begin

    //  Download the email by sequence number.
    email := imap.FetchSingle(i,bUid) As CHILKATMAILLib2_TLB.IChilkatEmail2;

    //  ... your application may process the email object...

  end;

//  Disconnect from the IMAP server.
