If you're "relaying" then all your relay does is pass communication
between remote DHCP servers and local DHCP clients (typically, your
PCs).  You may as well have those remote DHCP servers configure the
appropriate master DNS servers.  I don't see anything in the dhcrelay
man file about also relaying DNS data.

Relaying is required for DHCP to work across different networks (a DHCP
server responds to broadcast requests on its own network).  Some sort of
relaying is not required for DNS, the servers should be able to talk
directly to each other.
