The timeout is for the non-authoritative answer for the DNS lookup and not
necessarily a problem with your email server.

You could perform the request directly on the authoritative server:

nslookup -q=any xxx.com ns.xxx.com

This assumes ns.xxx.com is the primary DNS for xxx.com.

It's normal for query resolution to take more than 2 seconds
to perform for some particular domain names.
