I'm not sure I understand your question...traffic goes both ways.
Do you???
1. Want to allow internal hosts to connect to external pop3 servers.
2. want to allow external hosts to connect to internal pop3 servers.
note: external=internet
I'm assuming #1. There's not that much risk involved there. The users are only
receiving mail.
If you mean #2. That depends on your firewall setup, but it can be done safely under
some circumstances.
