imap functions

Hi there ! I have a problem with the text-body of a mail, when I read the given popbox. When the mail was send with outlook or other same mail-clients i have cryptic characters in the text of the mail, when i used the imap functions to list this mailpart. I have tried to decode the iso-8859-1 with the imap_mime_header_decode() function. But this function only work with the subject and the sender-email but not with the text-part of the mail. I don´t know which kind of decode i must use to list the part correct. The following sample characters are in the mail: m=F6glich sein. =20 Mit freundlichen Gruessen =20 Is there anybody who can help me with this problem ? thx Sebastian
