vodafone
Vodafone has shutdown the Italian vodafone.it and teletu.it email domains as of June 1, 2023, and has deactivated all mailboxes at both domains. The domains still have an MX record (as of June 26th) but neither MX is answering on port 25.If you’re an email sender, best to unsubcribe, suppress or delete addresses at this domain, in case they are ever resurrected in the future as spamtrap domains.More information can be found here.
As part of UPC’s sale of various assets to Vodafone, I am reliably informed that the domains upcmail.hu, chello.hu, and monornet.hu no longer host email users and should be considered retired. As of this writing, all still have MX records, but any attempts to mail those users will results in “550 5.1.1 MXIN501” errors.Thanks to Mailkit’s Jakub Olexa for this information!
