Hello list,
We are seeing some "mean" behaviour when sending an e-mail to any e-mail address ending in @
bluewein.ch. Note the difference between bluewin and bluewein...
As soon as an e-mail is sent from our relay to this domain, we get listed on the UCEProtect-Level1 blocklist. Yes, we can discuss whether or not this is a serious blacklist, but some mail providers actually use this service and then block our legit e-mails.
Now to this domain. On HTTP all seems in order, the domain is redirected to
bluewin.ch. But SMTP points to a separate mail server:
mail.ict-olten.ch. Behind
ict-olten.ch seems to be nobody (no website, no other results so far after a bit of research).
Does anyone here in the list have information about the behaviour of this domain and who is responsible for it? Obviously a typo "bluewein" instead of "bluewin" happens pretty fast when users are registering and it's already the second or third time within a month that we get blacklisted due to a typo from users.
thanks for any hints and cheers,
ck
