Is HTTP Post blocked from some servers when it is generated from PHP Code?
I would like to create a WordPress plugin which will do an HTTP post to send XML data to a service running on a remote server.

However I have been told that some servers prevent outgoing HTTP posts from PHP based code. Is this true? If so, is it possible to work around this issue?
