I just did a test submission on your English form and here is the email log:
May 21 22:26:16 yang sm-mta: p4M2QEfE030685: to=<info@email_redacted_by_me.com>, ctladdr=<email@example.com> (1004/1004), delay=00:00:02, xdelay=00:00:01, mailer=esmtp, pri=123406, relay=mail.studioredesign.com. [18.104.22.168], dsn=2.0.0, stat=Sent (Ok: queued as 7AE1E280989)
Basically, all this is stating is that the submission was sent to your email account okay. Please check your junk/spam folder or ask your email service provider what happened to the message whose ID is 7AE1E280989.
Please keep us informed on the progress of this issue.
P.S. As promised, your submission count has been reset to what it was prior to this test.
