The content of the folder is as followed: 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. And is from the mailer-demon@linux.local And were can i find more info to this subject. TIA Ralph Robinson icq 26003826
