Ted, that is a handy site.
 
A suggestion:  An issue that is not obvious to those who are not web/network administratiors is: "Where do I put the crossdomain.xml file".  While I bet this is discussed on more than one of the links you provide, consider a quick paragraph on the subject, for additional convenience.
 
The usual response: "In the root of the web server" is not enough for non-experts.  Include an example path for, say the default integrated Flex 1.5 install, one for a default Tomcat install, and one for a default IIS install.
 
I figured mine out by putting a full access crossdomain file in every possible folder until  my call worked, then deleting them until I broke it again.  This showed me the right place.  You see why I am not offering to provide the examples!
 
Tracy

Rogerio,

With Socket operations you will need to have a crossdomain.xml file on the server you are connecting to, in this case the POP server! This particular crossdomain.xml file needs to permit access to use low/high ports for inbound connections. It is identical to the process needed to support XMLSocket servers.
 
The use of crossdomain policy files prevents Flash/Flex clients from abusing other peoples servers. As permission is delegated to the server owner, they can decide what ports Flash Player can connect to.
 
Example:
 
<cross-domain-policy>
  <allow-access-from domain="*" to-ports="507" />
  <allow-access-from domain="*.foo.com" to-ports="507,516" />
  <allow-access-from domain="*.bar.com" to-ports="516-523" />
  <allow-access-from domain="www.foo.com" to-ports="507,516-523" />
  <allow-access-from domain="www.bar.com" to-ports="*" />
</cross-domain-policy>
 
 
I put together this small site on crossdomain policy files. It doesn't have any glits and gives you the bare bones knowledge on using crossdomain.

Subject: [flexcoders] POP3 by Socket
 
Bom dia pessoal,
Hi folks,

I want to know if anyone of you try make the POP3 by Socket example,
from IFBIN(Flex by Example), work with final version of Flex 2.
Now that he´s free, I try to test something but it just don´t work.
Don´t give me any errors. Seems to be a security issue, like
crossdomain, but I can´t figure out the real problem.

Thanks

Rogerio Gonzalez
