Using DNS Made Easy for your DNS (set other name servers at your registrar), combined with their SMTP Mail service should do the trick. Their support team is one of the best I have seen to date!
You can use alternative ports for incoming and outgoing mail using their servers to circumvent the ISP's restrictions.

Thanks Mark23. I'll give them a call. DynDNS is 'supposed' to do what these guys advertise, too... Maybe these guys use a different authentication mechanism and/or are more willing to help. Ideally, the Server GUI would offer some more configuration options... or there would be a resource that would help "connect the dots" in scenarios like this.
I'll follow-up here...

Enter this into terminal to get you going:
sudo serveradmin settings mail:postfix:relayhost_enabled = yes
sudo serveradmin settings mail:postfix:relayhost = "server.dyndns.com"
sudo serveradmin settings mail:postfix:luser_relay_enabled = yes
sudo serveradmin settings mail:postfix:smtp_auth_relay_dict:smtp_auth_relay_userid = "dyndns_username"
sudo serveradmin settings mail:postfix:smtp_auth_relay_dict:smtp_auth_relay_pwd = "dyndns_password"
Hope this helps

Did you find a solution to your problem? I have the same trouble with DynDNS and Mark23's last answer hasn't helped.
Something must be different with Mountain Lion Server because the connection to DynDNS' Mail Relay has worked well in Lion Server for me.

Not fixed yet. I didn't get this to work, either. I haven't given it the time needed recently. All my research pretty much summed up your assessment - "something is different." I'm sure some of the suggestions/solutions are correct, but they're just a tad 'above' my technical understanding so I'm not 100% sure of what parts I'm missing that some more technical recommendations assume I already know.
My ML server is more of a "hobby" that I tinker with... so it only gets time every-so-often. If I could figure it out - it would likely only house one or two email accounts. I'll report back if/when I get more time.

Seems the problem has been solved by Peter Rauen.
See this discussion: Mail relay SASL problem / postconf -n
I checked on my server and Peter is right. Although there are configs in /etc/postfix there is another path with postfix conf files: /Library/Server/Mail/Config/postfix
I actually only had to insert this line to main.cf there: smtp_sasl_security_options =
After a postfix reload my mails are being delivered via dyndns again.
