[Users] t_relay does not follow RFC3263 "Locating SIP Servers"

I have a question regarding the behavior of t_relay.
When the proxy forwards a request for another domain using t_relay it does
not use NAPTR and SRV records of the target-domain as stated in RFC3263
"Locating SIP Servers". Instead it expects a resolvable host-name for the
domain-part or the URI.

The following example:

	INVITE sip:andrea at fenet2.at

Causes the errors:

	ERROR: mk_proxy: could not resolve hostname: "fenet2.at"
	ERROR: uri2proxy: bad host name in URI <sip:andrea at fenet2.at>
	ERROR: t_forward_nonack: failure to add branches

There are NAPTR and SRV RRs associated with domain "fenet2.at" but SER does
not use these RRs. Why?

Are there any comments on this issue?
