I have a server by the name
svr1.domain.com which runs on a CentOS with WHM. I have configured its email service to pass through a relay while discarding any email generating through the server name (e.g.: an account named acc1 using cPanel has a wordpress which has a contact form. The contact form uses hosting's internal mail function upon some anon user submitting a query. Then the mail generates on cPanel as
firstname.lastname@example.org). Which means any mail generates as
email@example.com will be discarded.
Now, the question is; is there another way to over-come this issue so that these mails can by-passed or in-fact use some kind of SMTP mechanism to each cPanel account created through WHM?
