Who can update DNS for me?

google is rejecting our outgoing messages to gmail (and other hosted
domains), most probably because 2620:113:80c0:8::16 has no PTR record.

In the last 24hours, 1933 messages to 769 recipients were rejected.

Here is one of the bounces:

<james.knott@xxxxxxxxxx>: host
ASPMX.L.GOOGLE.COM[2a00:1450:400c:c04::1a] said:
550-5.7.1 [2620:113:80c0:8::16] Our system has detected that this
message does 550-5.7.1 not meet IPv6 sending guidelines regarding PTR
records and 550-5.7.1 authentication. Please review 550-5.7.1 for more
information 550 5.7.1 . s5si1908312wmf.81 - gsmtp (in reply to end of
DATA command)

They forgot to get the PTR records changed with MF IT ... for now we
went back to the old IPv6 address range on baloo and changed it in DNS
server as well.
