I have written a website that uses the PHP Pear Mail function to send a few email messages. Mainly to people who have lost their password and to me when somebody submits the "contact us" form.
My question is this: since I am sending the email from my own server's IP address to myself, do I use the client's email address in the From or Reply-To headers?
It would make sense to place it in the Reply-To header, because that is most definitely what I want to do.
However, many email clients seem to work best with the client's name and email info located in the "From:" headers.
Is it safe to "falsify" the From: headers in an email? Or am I even falsifying the sender?
I mean... technically... the client is sending the message, it's just originating from my server.
