Sorry for my english. I hope you will understand me:
I'm trying to configure exim-4.69 with libsfp2-1.2.5.
Exim receives Segmentation Fault while processing spf condition. It crashes
every time when the message should not be delivered.
I'm using 64-bit Debian Etch.
I tried to use:
 * Exim-4.68 and Exim-4.69 (compiled with libspf2, libsrs_alt and openldap)
 * Debian package libspf2-1.2.5-2
 * libspf2-1.2.5 compiled from sources with the default options (i.e.
configure; make; make install)
Every time there was the same problem.
I tried to debug it:
