Hi,
anyone else in trouble with hotmail.com again? We are a very low sending MX without any spam from our range. It started at 17:00 that hotmail was not offering TLS. I have no clue, why this is the case. Is this some kind of spam defense voodoo? Our MX tried again after an hour and got refused with "network is on our block list (S3150)" No blocklist shows our ip / network as blocked. Also microsoft owns SNDS shows no issses at all. Already requested unblock even though i do not see anywhere a block of our ip. This is all insane.
