Hello, two questions:

1. Thoug message_id i get the full pathname to the input msg, like
    /usr/exim/spool/input/3/M323SD-D, and than i open a fd to reading
    and then a i close the fd. local_scan completes ok, but soon after
    the exim daemon segfaults. On a strace to exim pid, i see it segfaults
    on a call:
    writing headers...
    fsta64(
    segfault...

    Anyone know why this is happen ? hot to fix ?

2. (in local_scan) How can i use an expanded string with $local_part to a mysql query ?
    Because the $local_part its not already set ? on mysql a get a "".

Thanks in advance...
Sorry for the english
