批量修改所有服务器的dbmail配置

最近遇到这样一个案例，需要修改所有SQL Server的Database Mail的SMTP，原来的SMTP为10.xxx.xxx.xxx, 现在需要修改为192.168.xxx.xxx， 另外需要规范邮件地址，以前这类邮件ServerName@yoursqldba.com的后缀需要修改为ServerName@xxxx.com(信息做了脱敏处理)。

如果使用SSMS客户端的UI界面去修改的话， 那么多服务器一台一台去修改，不仅费时费力，而且枯燥无聊。只能使用脚本，一旦写好一个脚本，而后使用Multiple Server Query Execution（极力推荐使用这个管理、维护数据库），执行一次脚本，全部搞定。剩下的时间你可以喝喝茶、学习下新知识！

DECLARE @EmailAddress NVARCHAR(120);
