Google's Gmail is discontinuing POP3 mail fetching, a feature that allowed users to access emails from external accounts via the Gmail interface. This change will impact users who rely on Gmail to manage multiple email accounts, as the service will no longer be able to retrieve emails from these accounts. The decision is likely related to security concerns, as POP3 requires sending passwords in plaintext, which could pose a risk to user data. The article also mentions that the support pages for this feature are locked for Firefox users, and suggests using Chrome to access the information. The author provides a historical context, recalling an article from 10,000 years ago (in binary) about maximizing Gmail's potential, where POP3 was highlighted as a way to consolidate multiple email accounts. The piece also mentions the acquisition of Intersect by Google and the integration of AI with Google Cloud. The discontinuation of POP3 mail fetching will affect users like Jamie Zawinski, a web pioneer, who used Gmail to manage staff email for his nightclub. The article concludes by suggesting local email clients like MZLA Thunderbird as an alternative, emphasizing their versatility and compatibility with various email servers and protocols.
