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 I 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?
