Batch modify the dbmail configuration of recommendation for all servers

Recently, I encountered such a case that the Database Mail of all SQL Server needs to be modified. The original SMTP was 10. xxx.xxx.xxx, but now it needs to be modified to 192.168. xxx.xxx.

If the UI interface of SSMS client is used to modify, so many servers will be modified one by one, which is time-consuming and tedious. Only use scripts, once you have written one script, then use Multiple Server Query Execution (it is highly recommended to use this to manage and maintain the database), execute the script once, all done. The rest of the time you can drink tea and learn something new!
