以数字结尾的电子邮件有效吗?例如

cat@cool.thing89

最佳答案

知道一封电子邮件由 [local section]@[domain section]...

An unbracketed domain consists of labels separated by periods and less than 253 characters.

Labels can be quoted or unquoted (unquoted labels must consist of a-z, A-Z, 0-9, or any of !#$%&'*+-/=?^_{|}~ or ` and have at least one character)

The right-most label must be all alphabetic.

...电子邮件不可能以数字结尾,因为域必须用括号括起来(用 [] 括起来)或以全字母标签结尾或以引号结尾。另外,这里是相关的 RFC:

The top level domain must be all alphabetic. (RFC 3696, section 2)
