    Domain to Dyndns to dynamic ip?

    Can you point a domain at a dyndns domain which points to a server with a dynamic ip?

    As in mail.newdomain.com > mail.dyndns.com > ip.that.like.to.change

    Or is there a much simpler way of doing things?

    Thanks

    would a cname work in this situation?

    MX record pointing to CNAME (mail.domain.com) which points to dnydns?

    And can you specify a non default port in an MX record, so mail is on port x instead of 25?

    I'm sure that is how I used to have my local charity when we got our SBS box and just had ISDN and no static IP, we had the domain and pointed it at something on DYNDNS's system and had a small app on the server that when the IP changed it updated DYNDNS and that thus then worked fine and was great for about a year until we actually could get ADSL and thus now have ADSL with a static IP

    I cant route directly out as my IP is dynamic
    The IP you're using to send mail is not authorized to send email directly to our servers
    Does anyone know of a free smtp relay or are willing to let me use theirs?
