Hi. I reinstall all system.
- DHCP - all good (web and mail)
- Web proxy - all good (web and mail)
- Web filter - all good (web and mail)
- Install pop3 proxy (not on) - not good (web - ok, mail - pop3 ok, smtp -error)
I dont know, I only install pop3 proxy, dont turn on and have error.
Web proxy - Transparent with SSL
Web filter - filter off, antivirus on
What am I doing wrong?
I only try to use linux system and my knowledge of Linux is not great. I have basic concepts. I can see the configuration files. If you need something else tell me.

I understand that somewhere I need to hurt something, but where?
