When I run
$ sudo netstat -a --programs | grep LISTENING | grep 1630
I will get this output. Do you know what good are processes running under this app name? Why they are running on my system and if it's OK to have them running?
$ sudo lsof -Pwn | grep 1630/master
founds no information
$ find /usr -type f -perm +111 -name master
Is this a security problem? I don't remember I have installed mail server. Could this be installed by malicious software? Can I remove if from running processes if I don't need it?
