Which email server is typically used for sending correspondence?

The selection of Microsoft Exchange as the answer is valid when considering its primary function in an organization for sending and managing email communications. Microsoft Exchange is a dedicated email server solution that provides a range of services including email, calendar, contacts, and task management. It is commonly implemented in enterprise environments where there is a need for robust security, large storage capacities, integrative features with other Microsoft products, and centralized administration.

Gmail, while being a popular email service, is primarily hosted in the cloud and is designed more for personal use or small to medium-sized businesses rather than as a comprehensive email server solution for larger organizations. Yahoo Mail operates similarly to Gmail, focusing on individual users and less on serving as a corporate email infrastructure.

Outlook, on the other hand, is an email client that interfaces with various email servers, including Microsoft Exchange, but it does not function as a server itself. It allows users to send, receive, and manage emails but relies on Exchange or other server solutions for actual email transmission and storage.

Therefore, Microsoft Exchange stands out as the typical choice for an email server specifically designed for sending correspondence in professional environments.
