In the previous mails, I wrote:
The remaining restrictions are that ... and that a set of port numbers available to the application layer is limited (you may not be able to run a SMTP server at port 25).

At the transport layer, end-to-end means you can establish connections on various ports to any peer on the internet, and any peer can connect to all ports on which you allow. It doesn't necessarily mean that all ports are allowed; a remote host, or a firewall under their control, deciding to block your connection is not a violation of end-to-end.
