When it comes to the English name domain application in postal service, we need to consider factors such as simplicity, memorability, and relevance. The domain name should be easy to spell and remember, and it should clearly represent our postal services. For instance, 'speedpost.com' or 'fastmail.com' could be appropriate choices.

For commercial management, we need to choose a domain name that reflects our core business activities and values. It should be unique and catchy enough to attract potential customers. For example, if our main focus is supply chain management, then a suitable domain name might be 'efficient SCM.com' or 'smartlogistics.com'.

As for intelligent manufacturing, our English name domain application should highlight our capabilities in this field. We can use keywords like 'AI', 'automation', 'robotics', etc., in our domain name. For example, 'intelligentmanufacturing.ai' or 'automatedfactory.com' could be fitting options.
