That fixed the all caps issue:

<?php
function imap_utf8_fix($string) {
return
iconv_mime_decode($string,0,"UTF-8");
}
?>

Use iconv_mime_decode();

<?php
// This yields "Subject: Prüfung Prüfung"
echo iconv_mime_decode("Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=",
0, "ISO-8859-1");
?>

You may also try this example:

$_subject = "=?iso-8859-1?b?THV6b26uMTQ=?= dot CoM";
echo utf8_decode(imap_utf8($_subject));

OUTPUT: Luzon®14 dot CoM

Also see:
<?php
imap_mime_header_decode
($sting);
?>
Don't try to decode subjects with this one... imap_mime_header_decode does a much better job at that.

Be aware: imap_utf8 tends to return the string in uppercase.
