Emails To Outlook.com Rejected By Faulty Or Overzealous Blocking Rules

1 week ago
Microsoft spent much of the past week rejecting legitimate emails sent to Outlook.com, Live, and Hotmail accounts due to what appears to be overly aggressive IP reputation filtering or faulty blocklist rules. According to The Register, many senders received 550 errors claiming their networks were blocked, preventing delivery of invoices, notifications, and authentication emails. From the report: A block list is a good thing. It helps stem the flow of spam from networks or addresses associated with junk email. However, the confusing thing for our reader is that his company was not on Microsoft's naughty step for email. A look at Microsoft's Smart Network Data Service (SNDS) showed no issues with the IP. "We're also a member of their JMRP (Junk Mail Reporting Program)," our reader added, "which is intended to inform us when people are reporting spam sent from our IPs - except, we never get any reports." The problem worsened in February. On Microsoft's support forums, users began to complain about similar issues as the IP net presumably widened. One wrote: "We are currently experiencing a critical and recurring email delivery issue affecting recipients at outlook.com, live.com, hotmail.com, and msn.com," and provided a copy of an error that suggested the mail server has been "temporarily rate limited due to IP reputation." The user drily noted, "Although the error indicates rate limiting, in practice no emails are being delivered." A large number of users, ranging from the administrator of a server sending automated notifications on behalf of Estonian Public Libraries to an email provider for healthcare professionals, chimed in to confirm they too were having delivery problems and Microsoft support was not helpful. [...] Unsurprisingly, our reader spoke on condition of anonymity - nobody wants to be the ISP that has to say, "Yeah, we can deliver your email anywhere but Outlook.com" to customers. We asked Microsoft to comment, but other than acknowledging our questions, the company did not respond further.

TikTok Says End-To-End Encryption Makes Users Less Safe

1 week ago
An anonymous reader quotes a report from the BBC: TikTok will not introduce end-to-end encryption (E2EE) -- the controversial privacy feature used by nearly all its rivals -- arguing it makes users less safe. E2EE means only the sender and recipient of a direct message can view its contents, making it the most secure form of communication available to the general public. Platforms such as Facebook, Instagram, Messenger and X have embraced it because they say their priority is maximizing user privacy. But critics have said E2EE makes it harder to stop harmful content spreading online, because it means tech firms and law enforcement have no way of viewing any material sent in direct messages. The situation is made more complex because TikTok has long faced accusations that ties to the Chinese state may put users' data at risk. TikTok has consistently denied this, but earlier this year the social media firm's US operations were separated from its global business on the orders of US lawmakers. TikTok told the BBC it believed end-to-end encryption prevented police and safety teams from being able to read direct messages if they needed to. It confirmed its approach to the BBC in a briefing about security at its London office, saying it wanted to protect users, especially young people from harm. It described this stance as a deliberate decision to set itself apart from rivals. "Grooming and harassment risks are very real in DMs [direct messages] so TikTok now can credibly argue that it's prioritizing 'proactive safety' over 'privacy absolutism' which is a pretty powerful soundbite," said social media industry analyst Matt Navarra. But Navarra said the move also "puts TikTok out of step with global privacy expectations" and might reinforce wariness for some about its ownership.
