High load (uptime 100+) on dedicated server. Need help with settings

Hello,
New to the forum and hope someone can help. We have a dedicated server with a single processor and 1GB RAM. The site is pretty responsive, but the uptime/top numbers are VERY high and I'm having trouble sending and receiving email. (Open WebMail ERROR - Couldn't open SMTP server 127.0.0.1:25!)

I'm new at this and took some settings from other threads in hopes that it would help, but it's still really high.

$ netstat -ant | grep :80 | wc -l | awk '{ print $1
813
