Newbie question

[Per-fredrik Pollnow (EPK)]

Hi,

I have been looking around on the Inet to see if I could find anything about how I 
secure qmail pop3 service, but I don't have a ??? and I don't find a ???..
I was wondering if anyone have some good ideas what to use or where I can find some 
information about securing qmail pop3 etc. (Right now I'm using qmail-pop3d on 
OpenBSD).

Thanks
