After https://phabricator.wikimedia.org/T88204, beta wikis send out mails with $domain part set as beta.wmflabs.org.
But these wont come back still to deployment-mx as
$ dig +short -t mx beta.wmflabs.org $
returns null. Should we be adding deployment-mx to the mx-records of beta wiki ?
Looks like mx records are maintained in LDAP.

We can add a similar mxRecord entry for beta.wmflabs.org.

I added an LDAP entry from terbium:
mxRecord: 10 mx.beta.wmflabs.org to dn: dc=beta,ou=hosts,dc=wikimedia,dc=org
