Dear Stan,
I doubt it is absolutely necessary to pay for that service.
Please refer
Yes, it is necessary. You can't host a mail server without paying someone
some amount of money. If you actually _read_ my previous email and followed
the links, you will see the page on dyndns.org that sells the mail forwarding
service for $49.95/year. You can't get your email routed to your mail server
_through_ dyndns.org without paying for one of their mail forwarding services,
the cheapest one being $49.95/year.
Wrong. All you need is a free foo.dyndns.org hostname. And a
server with internet of course.
If you want to use your own vanity/business domain rather than
a foo.dyndns.org or similar free domain, you'll need either a
static IP or paid "custom" dynamic IP service.
Using TZO and your own domain is an alternative. It costs a little more per
year but you don't have to have TZO or anyone else forward your mail to you.
Because you have your own domain, TZO let's you create an MX record, which
dyndns.org does not allow.
There are other options available, other providers of these services. Some
services are free, some are not. Email is one that is not. Not for
dyndns.org, not for any free dynamic dns provider.

None of the suggestions in that forum thread are true. The guy who said he
had it working simply by "not checking the box on their site" is full of crap.
Lying, pure and simple. Why? Go ask him.
Stan, you're wrong here. All you need is an A record pointing
to your server. You get that for free with dyndns and other
free dynamic IP services. Dyndns also allows you to set a
"custom" MX record pointing somewhere else for free if you want.
Remember, RFCs specify that in the absence of an MX record,
the A record is to be treated as a 0 priority MX record. An
MX record is not required to either send or receive mail.
The thread conversation is a little convoluted, but
essentially correct.
If you're on the postfix list you should already know by now the basics of
mail routing for domains. If dyndns.org users want to get mail to their
subdomain routed through dyndns primary domains, they _must_ pay for it. Why?
Because it has to be manually programmed into dyndns.org's MTAs. If it's not,
your mail doesn't get to your MTA. This is very very simple.
Don't confuse mail routing (mail directed from the internet to
your server via DNS records) with mail hosting (mail accepted
somewhere and forwarded/proxied to your server). Dyndns
provides mail routing for free; their mail hosting service is
a paid service.
An important note here is that hosting mail on a dynamic IP is
full of potential problems; you'll need to relay your outbound
mail through somewhere such as a google account or your ISP,
and your there is the possibility of your incoming mail being
misrouted temporarily in the time between when your IP changes
and the update propagates through the worldwide DNS system.
