which programm creates file "Junk-E-Mail"

[snIP3r]

hi all!

i am wondering where the file "Junk-E-Mail" im my user's home directory comes from? the format of the file looks like mbox format and it seems that spamassassin is creating this file, because ther's only spam in it. but using pine does not show the file's contents.
im using the following mail programs and tools:
sendmail, fetchmail, pine, procmail, spamassassin, clamassassin

here's a part of the file:
From MAILER-DAEMON Thu Jun 10 09:50:01 2004
Date: 10 Jun 2004 09:50:01 +0200
From: Mail System Internal Data <MAILER-DAEMON@area52.restricted-area.de>
Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Message-ID: <1086853801@area52.restricted-area.de>
X-IMAP: 1084997025 0000000017
Status: RO

This text is part of the internal format of your mail folder, and is not
a real message. It is created automatically by the mail system software.
If deleted, important folder data will be lost, and it will be re-created
with the data reset to initial values.
....

any ideas??

thx & greets

This message is created by Pine. See here:

Quick summary:
What is this DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA message all about ? How do I get rid of it?

That is a pseudo-message placed by Pine in your mailboxes. It serves several functions: It saves state for messages across IMAP sessions. It helps define the format of an empty mailbox. There are no doubt other uses.

Pine ignores this message, and automatically suppresses it from message-indices. Other mailers unfortunately do not. If you want, you can suppress this message altogether by setting the following option:

[X] quell-folder-internal-msg

You should read the online help for this option before you set it, to make sure you understand the implications of it, and what features you will be losing.
