This is bad because you're trying to do it with DynDNS. This prevents you from being able to setup a standard internet mail host with MX. > All I'm trying to do right now is send and receive email messages through my > free DynDNS account. Let's say it's subdomain1.dyndns-free.com . Docs for this are available at dyndns.org. You will need to use their mail forwarder. > The OS is Debian Lenny. The mail server is exim4. The OS/smtpd don't matter much here, as long as you know what parameters to configure. > Let's say that the host name listed in my /etc/hosts file is > subdomain2.domain.com . The only thing that matters is that this hostname match the Exim config for "local domains" and that dyndns be told this is the hostname to forward mail to. > I have been able to run the exim4 configuration script by entering > "dpkg-reconfigure exim4-config".

I can't help you here as I'm a Postfix user, not Exim. > Do I need an MX hostname? There are so many unknowns that I don't know where > to begin. MX records are for second level domains, thus you can't us an MX record in this case as your system is a third level domain. The MX records in your case are for dyndns.org, your parent domain. Now, all of that said, there is a way you can set this up to work with a real domain and MX record so mail is delivered directly to your server. To do this, register a domain name, your-domain.com, with any registrar, and setup a DNS hosting account (most registrars offer DNS hosting today, as well as mail, web, etc). Create a DNS MX record pointing to subdomain1.dyndns-free.com, and configure Exim to accept mail for the domain "your-domain.com". Now, any time anyone sends mail to your-domain.com it'll go directly to your Exim host. Depending on which domain you register, it'll cost you anywhere from $5-$15 USD/year for a cheap domain. I pay ~$15 USD/year for my vanity domain. I've had it since 2002. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
