[exim] remote_smtp defer (-53):

I have this problem:

Example:

2005-09-20 18:17:13 IN4LCP-0002D8-79 <= xxxxxxx@??? H=localhost (stardatamain) [127.0.0.1] P=smtp S=1329 id=000f01c5be07$2446b7b0$693b81d9@stardatamain
2005-09-20 18:17:13 IN4LCP-0002D8-79 == xxx@??? R=nslookup T=remote_smtp defer (-53): retry time not reached for any host
2005-09-20 18:17:16 IN4LCP-0002D8-79 => xxx@??? R=nslookup T=remote_smtp H=mail.fraglider.com [213.63.xxx.xxx]

This message is sent to 2 diferent email adresses and the addresses from the domain netvisao.pt do not receive due to the error ( in fact this domain is the same were i have the server)
And i can send emails to all other domains and it works but for this domain doesnt.

I Also tried to set up as relay to smtp of my domain but the denied the relay.

Can someone give me an hit or help me with this problem??



Thanks for the attention.
