Postfix Mail Server with Dynamic IP Address by DSL

turiyain · 11-02-2009, 04:26 AM

Dear Experts,

I want to configure a postfix mail server with postfix admin, dovecot,amavis, spamassassin, clamav. I am having a DSL Modem and a registered domain name. Now I want to set up my mail server online with my current resources. My question, that can i set up my e-mail/web server without purchasing a live IP. I heard that this is possible without the Live IP. But i am not sure.

Please help ..
Thanks in advance.

What's a "Live IP" ?? Generally you can put an SMTP server on a service like DynDNS or noip. As for outbound traffic you might need to route SMTP data via an upstream ISP MTA, as other ISP's may well block traffic coming directly from a dynamic IP.

I am having DSL Connection with dynamic static IP which changed after some hours. At this point i am not sure that how to use dynaDNS or any setting at postfix level. This is my first e-mail server so i need some basic steps.

Is there any web link where all related information can be found.

not really, you are taking lots of unrelated things, e.g. Postfix and dynamic DNS need know nothing about each other whatsoever, so just get each constituent part working one at a time.

To sent mail via SMTP, you need a fixed IP
Most SMTP servers refuse connections from dynamic IP's
However, you can confiure postfix to use your providers SMTP as smarthost.

To recieve mail, you need a domainname, the MX records from that domain need to point to the IP of your server, also you need to setup reverse DNS
Also, you need to make sure your provider doesn't block port 25

My 2 cents, setup postfix with as smarthost the SMTP fom your provider, and get your mail using fetchmail.
