Re: I have been hacked (WAS: Have I been hacked or is nmap wrong?)

Also, I said smtp ports were open on the machines in question, I just verified that I can send emails via BOTH these systems even though no sendmail/exim/whatever was ever installed by me and sendmail_enable="None" on both. 

For what it's worth, to disable senmail on 5.0 and later, you need:

sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

All those lines need to go in your /etc/rc.conf file, just the top line on it's own will only stop mail coming into your system and I think it has to be "NO" not "None", but I'm not 100% on that.

The above is from the Handbook:
