Unable to start playsmsd

some times back I installed playsms and started service on windows 8.1 without any thirdparty like cgywin. but there was a problem of postfix that sends mail outside.

centos/linux and ubuntu is a good environment to start successfully playsms, I have a live setup also, and working good.

playsmsd start

where is your playsms installed
