bilis_money Posted July 13, 2006 Share Posted July 13, 2006 Hi, i'm wondering if it is possible to determine an e-mail address if it iscurrently existing or not?And also how to distinguish if the e-mail is using spam blocking system.If this possible then what PHP e-mail functions related to this topic?Thank you very much in advance.

zq29 Posted July 13, 2006 Share Posted July 13, 2006 I don't think you will be able to do this without sending an email to the address and checking for bouncebacks.

pixy Posted July 13, 2006 Share Posted July 13, 2006 The best way to do it would probably be to send the email some sort of activation. If you're using it with a user script, you could just have a field called activation with a random string in it and give them a link to click so it activates them.Other than that, I don't know.

nogray Posted July 13, 2006 Share Posted July 13, 2006 I think you can do it without sending an email, but with communicating with the mail server, check this tutorial in zend.comhttp://www.zend.com/zend/spotlight/ev12apr.phpThe problem will be if someone entered a valid email, but someones else. So sending an email and require validation will be the best option.
