In 1995, telnet was used, too.

I think that it would be totally wrong to implement this. IMAP is the way to 
go for this. Just because Netscape did this (IIRC the only client program 
doing so) does not mean in any way that it was smart. It is highly 
inefficient. Additionally, most POP3 server use a mbox file for storing mail. 
Every time, you check/get mail and do not delete it there makes it more 
inefficient and slower to look for new mail. Well, the POP3-Servers that use 
Maildir can do this a bit smarter but all such servers (AFAIK) that use 
Maildir also offer IMAP (and both with SSL).
Well, there are things like uw-imapd (mbox based)  but noone really wants to 
use that (assumption: except those that do not know how to get Maildir 
working).

And wow, Netscape <6 could not even do POP3S. This means that every time you 
deleted a mail, it was sending you username and password as clear text 
through the net (collecting the delete requests would be no reliable way, I 
guess).
This feature would also need a track of the server that the locally saved mail 
was from. IIRC, Netscape only offered that mail for the Inbox of the Server 
but KMail does not work this way, especially with filters applied.
Again: you really want to think this over. This is totally bad habit and 
should be avoided. If the KMail developers ever implement this, they did not 
think it over enough.
