/^[0-9a-z+_\.\-]+@([0-9a-z + _ \。\ - ] + \。)+ [az] {2,4}


Or
/^[0-9a-z+_\.\-]+@([0-9a-z+_\.\-]+\.)+[a-z]{2,4}


/ i


尽管我我不确定

电子邮件地址中实际允许哪些字符。


使用上面的代码。@ ...%0dBcc:sp ** @ example.net; mo ** @ example.net似乎是一个

完全有效的电子邮件地址..

再说一次,我不知道在验证的地方,它可以是

就足够了。

/i

Allthough I''m not sure which characters are actually allowed in an
emailadress.

With the above code .@...%0dBcc:sp**@example.net;mo**@example.net seems a
totally valid emailadress..
Then again, I don''t know where the validation is for, it could be
sufficient.
