SMTP behind NAT

Hi Guys. I'm currently in a nat environment, where outbound connections to smtp and smtps are blocked by a firewall. You are therefore forced (unless using vpn or something alike) to send mail via a local smtp server. I was wondering whether there is any sense in blocking these connections. What does the administrator gain by forcing everybody to a local open smtp server? Can you avoid being put on some kind of blacklist by these means? I would very much appreciate an answer. Thanks in advance. Best regards, Georg Pichler
