authoritative or not?

[beetle bailey]

I checked the logs but I guess I didn't look closely enough.  The subdomain 
in question failed because of invalid chars in host names.  I have another 
question though: the initial problem we saw was with remote mta's not being 
able to resolve this particular subdomain, but I checked what was listed as 
their authoritative namerservers and they were able to resolve soa queries.  
I guess I have two questions: if our nameserver fails to load a zone, how 
does it respond to queries? (is the data cached?)  Also, and I don't know if 
this should go to comp.mail.sendmail or not, but if the ns for a domain can 
resolve ours, why would their mailserver not accept mail from us? thanks.
