The situation where messages are temporarily held before delivery within Google’s email service can be understood as a waiting line. This delay, often brief, occurs as messages await processing and transmission to recipients. For example, if a user sends numerous emails in rapid succession, some may be placed in this temporary holding state until resources become available for immediate dispatch.
This mechanism is vital for managing email traffic effectively, preventing system overload and ensuring the reliable delivery of messages. Its implementation dates back to the early architecture of email systems, addressing the inherent asynchronous nature of electronic messaging. It contributes to the overall stability and performance of the Google Mail infrastructure, safeguarding against potential disruptions from high volumes of outgoing messages.
