How To check email existed or not

[Raghuvasa]

Hi All,

I have developed one web application
in that i have one user registration application and having fields like name dob and Email id.

if the user specifies any email id then we have to send a mail to specified email address. sending mail is ok.


but before this i have to check the specified email id is existed or not
i mean domain and address were existed or not.

and if mail id is not correct then we will get a failure notice but i want to
find the response if it is failure. not failure mail.



How can i do it.

Hi Raghuvasa,
You can use javax.mail.internet api for checking the validity of EmailAddress like this below.

Gothru below link
InternetAddress (Java 2 Platform Ent. Ed. v1.4)

InternetAddress address = new InternetAddress("specify the address");

address.validate();

but before this i have to check the specified email id is existed or not
i mean domain and address were existed or not.

If you mean whether an email address exists (ie does blah@blah.com exist), you can't. There's no reliable method for doing that.

Send a validation email with some kind of secure generated code that the user must then enter.

Of course, won't work with one-time email addresses.
