This isn't a postfix problem. If you can't telnet to any client port 25, then you have a connectivity problem; maybe your ISP is blocking that port, or some firewall has been misconfigured. Contact your networking team or your ISP. If you can't telnet to this one destination port 25, they're blocking you. You'll need to contact them to get this resolved. Good luck. -- Noel Jones
