I'm installing qgreylist . It uses perl and uses Sys::Syslog. However, it's not working and I notice the ff on syslog:

Sep 2 01:30:05 li164-183 kernel: greylist[345]: segfault at 10 ip b776692e sp bf856f60 error 4 in libperl.so[b773d000+161000]
Sep 2 01:37:11 li164-183 kernel: greylist[348]: segfault at 10 ip b75d492e sp bfbf5f70 error 4 in libperl.so[b75ab000+161000]

Anyone who could suggest to fix this? I can't contact anymore the author of the script.
