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?

Well, you've found the executable. It is part of postfix (email server). If you need that it's ok. If you don't, stop the service. – Mat Apr 12 '12 at 19:26
