AI-generated summary
This is a guide on how to obtain the MX records for a specific email domain. It suggests using nslookup and setting the type to MX to retrieve the records. The process involves DNS queries and recommends using the pydig.py module in Python to achieve this. By obtaining the MX records, one can set up a complete email system with SMTP clients and servers. The author mentions that most email domains can be used except for a few like 126.com and 163.com.

Email: xxxx@qq.com

By using nslookup, set type=mx

You can retrieve the corresponding MX record.

The principle is to query through DNS.

Find an existing module, pydig.py, which can perform DNS queries.

It can be called in other Python modules to obtain the MX record.

In this way, a complete system for sending emails directly between an SMTP client and server is established.

After conducting some experiments, it was found that most email domains can be sent to, except for a few like 126.com and 163.com.
