Last week i noticed the following running on my server. spamd 5073 root 4u IPv4 1010334 TCP localhost:783 (LISTEN) It was interesting that i never noticed it before then after looking around realized this was some kind of port opened by the new version of Exim. Its nice to know that there is another port listening but why? What is its use? Where can we find out more information on it? Should i allow it thru my firewall? How secure it is if i open this port on my FW? Many questions and we can only guess about. Again, i would personally like to be able to control what gets updated on my server evertime there is an update. Not so much the rpms but services like Exim, Interchange etc. I think its important when you consider that we may have our own customized mods running.
