With this help i could track the problem down. The path is set correct
but I have an other problem: the code is executed but fails. This is how
IMP tries to send the mail:

if (@is_executable($default->path_to_sendmail)) {
        $from = escapeShellCmd($from);
                $mail = popen("$default->path_to_sendmail -i -f$from --
$recipients", 'w');
                $result  = fputs($mail, $bhdrs . $hdrs);
                $result += fputs($mail, "\n");  // trailing \n to end
the headers section
                $result += fputs($mail, $body);
                if ((pclose($mail) >> 8 & 0xFF) != 0)
                       $result = 0;
        }                     

I set the $default->path_to_sendmail to exim (since I have no sendmail
installed anymore). When I try to debug the whole thing I get the
following line:

/usr/exim/bin/exim -i -fjs9@??? --
js9@???

This is what the IMP executes as pipe. But it doesnt work. The mail is
not send via this one but via the fallback the php mail function which
does not set the return-path correct.
If I try this line as wwwrun user every thing works fine. I have no clue
whats going wrong... But I think it has to be a php prpblem...

Any ideas to this one?
