How to get rid of that stupid "DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA" ?!

I have read many posts about the "DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA" message you receive when you use both IMAP and POP3 on this dboard but did not find any real resolution. Honestly, this problem is driving me crazy.

I should explain my situation...

There is a 'special' anti-spam PHP script running on my server all the time and this script connects to all email accounts through IMAP, checks if the sender has been authorized to send you emails and so on.

Then you setup your email client software to connect to your email account through standard POP3 protocol. Everything works just fine except that with every or almost every message you receive you also get that damn "DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA" message.

I need to get rid of that message, no matter how! It is apparently a message created by IMAP, but then becomes a part of the inbox file which is also used by POP3 which then thinks it is just a standard email and downloads it.

I am just wondering why the IMAP software programmers did not think about this problem, especially when it seems to be so common...

So my question is: What is the best way to get rid of this annoying message? Somewhere I have read that some POP server software can deal with this problem, for example ipop3d but Cpanel uses cppop.

Another option would be to set some filters to block all emails with that particular subject line but I tried the standard Cpanel spam filter and it did not work, probably because the message is sent from the server itself so it ignores all filters.

Or there could probably be a script, executed through Cron, that would scan all inboxes for this particular message and would delete it.

Or if there was a way to mark that message as Read / Seen so that POP would ignore it.

Please let me know what could be done, I really need to solve this problem!
