Email validation...please please help.

[healy787]

Hi people,

 

I have a client who is receiving numerous random emails through an online contact form. The email addresses are non existent and the content is jargon. I validate via javascript. I need a way to validate the email address...DNS validation???? The example email addresses they are receiving are vkefdw@akwmgn.com, the content is much the same. I am using standard CAPTCHA validation as well which i know has been broken however i believe email validation would help.

 

 

Thanks very much

 

Matt

Define email validation. You mean check if the format is correct or check if the email address exists?

Sorry...I have the standard validation which checks the characters, etc.  I need to ensure the email address exists or possibly exists. Thanks.

http://www.zend.com/code/codex.php?ozid=449&single=1 bit more complex for the noob but that code goes an interrogates the server the email box is held and asks it if it would accept an email to that address.

 

Many have catch alls so it could be that the actual email doesn't exist but it will be sent somewhere. what It WILL give you is if the response from that server says the address soesn't exists then it definitely doesn't exist.

 

come back with any questions if you need to. enjoy
