Sending email without having password

Hi,

Using PHP if I need to send the email using any email ID then I need username and pasword as minimum requirement.

But there is also one another method.
I wonder how it works ..
Can anybody tell me ?

There is one site http://www.lettermelater.com/
If you register using your email ID then it will send you a verification email.
If we verify it by clicking then it adds that email address to its account. Which is then used as FROM field .
Allows you to send emails to anyone you wish, with the ability to have them sent at any future date and time you choose.


Could any one please explain it . How do they able to send emails using our email address , without having users password . ( Just having verification using a link )

Regards,
Shirish

This probably doesn't send the e-mail from your account. I'd have thought it just sets the 'from' and 'reply to' parameters to your e-mail address, so it looks like it's from you.

which is why email headers are important as they say who it is actually from. lots of time i get spam coming thru because they are from 'myself@mydomain.com'.
spam detectors algorithm haven't figured out that loop hole yet, and consider you emailing yourself as perfectly alright, kinda like you talking to yourself. :crazy:

Thanks for your kind info.

I guess it has something to do it with SPF .
