[Spce-user] IM support?

[Jirka Jirout]

Hello,

one step further with deployment, I am now trying to get instant messaging working. My client sends a message over TLS and LB fowards it to Proxy like this:

> ##

The proxy responds by 100 - Trying, followed almost immediately by:

> #

As far as I can tell, the MESSAGE has all the fields necessary - and more. Is it possible that these extra fields cause the delivery to fail?
