Hi All,
Here is my "nearly solution" for this issue.
I have change the line
$result = $IMAP->search($mbox, $search_str, $imap_charset, $_SESSION['sort_col']);
to
$result = $IMAP->search($mbox, $search_str);
in the ..\program\steps\mail\search.inc
and now it works!
However without German 'Umlaute' (like ä,ö,ü,ß). I guess the problem is the charset ( UTF-8 ) ....?
Best Regards,
jolic
