I have a contact form page, which along with the rest of the website is hosted by PlusNet on the Plesk webserver. Every now and again when someone fills in the contact form and submits, the ‘from’ email address come though with firstname.lastname@example.org - or something similar with ‘plesk-host03.plus.net’ in it. Usually the senders actual email address is also included (see attached). Does anyone know what is happening and why this should be? The URL to the form is: http://www.typarke.co.uk/contact-us/contact-us.php. Many thanks.
