Hi. I am on Ubuntu 9.04 and used the Perfect Server how-to on this site. I am trying to configure an e-mail client to send messages using the SMTP client on my server. ISPConfig shows that the server is up and running, and I have port 25 open in the ISPConfig firewall and I have port forwarding set up on my router. It seems like those should be all the steps, but my e-mail client tells me it cannot reach the server. Is this not supported?
