Maybe I should have gone a database way. But knowing the speed of 
TAvlTree from fpspreadsheet, I store the decoded mails in this structure 
(a simpler TList should do as well), and create two index AvlTrees for 
the MailID and the ReplyToID. The TVirtualStringTree at the left of the 
form has pointers to these mails in its node data. The file finally is 
written and read by using the built-in methods of the virtualtree.
