Hi,

I need to know if is possible to send mails from one mail who are not the owner of the domain,

I mean, is possible to send mail from name@domain.com in xxxx@gmail.com?

This is an example in spanish (sorry)

"Antes de que puedas enviar mensajes desde XXX@domain.com usando tu cuenta Gmail (XXXXXX@gmail.com), haz clic en el siguiente vínculo para confirmar tu solicitud"


whith that i assume that is possible, but what happend if the domain.com is deleted? can i still send mails with that?

I'm not sure if explained myself....

Kind regards

So you want to forge your headers to make it appear that your mail came from a different domain than where your e-mail address is located?

That won't work. Some mail servers MIGHT let you actually send it, but any decent incoming mail server will look at the headers for the incoming message and compare it to your "From:" header, and if they don't match, the message will get flagged as spam.

This is by design in order to prevent people from hijacking other domains. Otherwise, I could send a message through gmail but say it's from "bill.gates@microsoft.com".

My problem is, i'm the legitimate owner of one domain, and i saw that messege in one mailbox.

If i change the DNS to point another server, they can still send mails with that system?

what can i do to prevent my domain to use like that?
