There are a number of things to know about email forms.
1. The from email address should be an address that actually exists as an inbox or forward.
2. Set up domain keys and spf records. Go to cpanel. Under Mail you will see Mail Authentication. Click that icon and Enable them both.
3. If the customer who is receiving the email from the form is on our server there is no issue. However, if the customer uses another email address it may be best to establish the noreply@customersdomain.com inbox as an actual inbox. Next, you set up a forward for the noreply@customersdomain.com to go to :fail: No such person at this address
4. All forms should be tested to make sure the client is receiving their forms without revealing an email address that can get spammed.
5. Many spammers harvest emails by submitting a bogus form and waiting for the reply or auto reply to see what address they can spam.
