For a new business, I need to run my own SMTP server out of my home. I can't use the SMTP servers of either our web host or our ISP because of limitations they place on outgoing emails. For example, our web host limits as follows:
1000 emails per day
< 500 emails per 5 minute window
100 recipients per email
Now, I've got two iMac's running OS X Snow Leopard and I understand postfix is available. I've just converted our FIOS Internet to static IP. Does anyone know of a resource that will help me make one of my machines an SMTP server and allow me to use Mail.app as the client to send the messages through the server?
Note: I've seen the following messages but they still use postfix in conjunction with a relay SMTP. How do I avoid the web host / isp SMTP server in sending emails?
