的唯一方法是发送电子邮件到该地址;即使这样，你是不是100％肯定。
The only way is sending an email to that address; and even then, you're not 100% sure.
- 在该地址可以被垃圾;没有人检查它。
- 在邮箱已满（暂时？），你会得到一个DSN
- 在SMTP服务器故障/中断
恕我直言，继续检查域（去容易的连接，如果你不想让黑名单）和类似的Akismet / Spamhaus的反垃圾邮件工具来过滤用户subsmissions。
IMHO, keep checking the domain (go easy on connections if you don't want to get blacklisted) and antispam tools like akismet/spamhaus to filter user subsmissions.
