On further thought, you may often be stopped by reverse DNS lookup by
the addressee host.  Reverse DNS lookup is a kind of authentication
that would not succeed without a static IP.

Note that there's nothing about SMTP that inherently requires DNS.
SMTP is defined to work with IP addresses alone.  However, servers may
be configured to disallow this.  That's the default for exim, I think.

Sorry to mislead before.
