[GTALUG] Spamhaus block

[Marc Lijour]

Happy to report that OVH got it fixed for me. They replied to the support
ticket within 24 hours. After two interactions we were done. They said it
took some time for the reverse DNS to replicate (for the reverse record I
did setup days earlier). Whether it was just that delay or they did
something in the backend, the dig -x command now reports the correct
information. No Spamhaus red flag since then. Happy end.
