As far as I know and may be Im wrong the mail server looks for the mx record, if it doesnt find one it looks for the A record. You just need to enable the dyndns pro (its the cheap one).
You may try with just the A record dont pay anything just set it up and test it, you have nothing to loose right? Saludos Ing.

Its about 1 usd or something like that. The only one I saw was $30 Then you set up you domain which is a subdomain of their own (yourdomain.dyndns.com or something) and it changes everytime your ip does. You just need to install a client. I hope this helps. Happy holidays. Saludos Ing. Alfonso Alejandro Reyes Jimenez Coordinador de Seguridad - SASI E-mail: aare...@scitum.com.mx Telefono: 91507489 Movil: (044) 55 85 81 04 62 De: .

The first difficulty I had after installation of Postfix was about the Static IP address problem. My IP address isn't static and I don't want to pay for one either. Can Dynamic IP addresses be used with Postfix? NoIP.com mentions some sort of stuff about it. > It's all about mx records. Your certs resolve to fqdn. What does that mean? Can I get and send mail using a dynamic IP address and my own domain name? MX Record stuff- how do I configure it for a dynamic IP address. > Some companies can make your mx record follow the ip. So how do I configure it? Any ideas? >>
