IMP with PHP as CGI

Until a couple of days ago, we were running IMP on our server with PHP compiled as an Apache module. Because we wanted to use the apache SuEXEC wrapper, I compiled PHP as a CGI, which works mostly fine. Every user on our web needs to put the following wrapper in their cgi-bin directory to be able to use PHP: #!/bin/sh export SCRIPT_NAME=$REDIRECT_URL export SCRIPT_FILENAME=$PATH_TRANSLATED exec /usr/local/bin/php But now we have a problem with IMP and mail attachments. When you view a mail message with attachments in IMP, it gives you an icon with a link to the attachment, which you should be able to click on to get the contents of the attachment. The URL pointed to is something like: http://server/horde/imp/view.php3/attached-file.bin?mailbox=INBOX&index=171&bodypart=2&actionID=13 This works fine when PHP is compiled as a module (view.php3 is read by the PHP module and attached-file.bin is sent to your browser), but when running as a CGI, PHP tries to open the file view.php3/attached-file.bin, which of course does not exist and it fails with error code 255 and not displaying anything (which I think is a bug in itself, it took me a couple of hours to figure out at all what is going on). Any idea how I could fix that?
