qmail-0.0.0.0.patch
tarpit.patch
quando ele vai compilar o ./chkspawn da o seguinte erro
Oops. Your system's FD_SET() has a hidden limit of 1024 descriptors.
This means that the qmail daemons could crash if you set the run-time
concurrency higher than 509. So I'm going to insist that the concurrency
limit in conf-spawn be at most 509. Right now it's 1000.
make: *** [spawn.o] Error 1

to usando o suse 9.1
gcc-3.3.3.41
glibc-3.3.3-98

Valeu,
Chuck

opa....editei o arquivo conf-spawn e mudei
de 1000 para 509. FUNCIONOU!!!

Valeu
Chuck
