Hi I have online forms on my site and when I receive one, the mail is "from" my sites email address. The real senders address is in the body of the message. Problem is when I hit reply, it will send the message back to myself and not the sender. Any answer will be appreciated.. Thanks...
Why don't you change the form, if you are using Wordpress then there are many plugins, one you can use and test first, if it is working good.
Which email client are you using to reply? Stop being lazy, and copy the proper email from the body of the message to the Reply field in your email client. Easy as that! There is no way to have your form generator to email from the senders email if they are using your website to send the mail. Hope that helps.
