Yes, absolutely, provided the set of MTAs this server will communicate
with is known to be IPv6-capable. Postfix works just fine with
IPv6-only in internal deployments.
If, however, you want to receive and send email to the Internet at
large, sadly you will not be able to send mail to, or receive mail
from, many potential destination domains without an IPv4 address.
