I have a question regarding transport gateways.

I have a jabber account a one of the Jabber servers. Via a desktop client added the msn gateway.

On the Jabber account setup on the N900 the only way I could get msn contacts to show up for the first time was by connecting to server msn.[someJabberServer.blah]

Should this be the case or should I be able to just put the base Jabber server name [someJabberServer.blah] and depending what transports/gateways I have registered all contacts show automatically?
