Did not receive an email after filling my contact form in my website for example and my virtualmin server

Hello everyone,

I am new here in this forum. I am having a problem about why i did not receive email from my website after filling contact form and my virtualmin server as well. Before i explained further, i give you a clue about my problem which should be that someone help my problem. My clue problem is:

• I used a CentOS 64-bit as my vps

• I used a Google Apps for email, so my MX record are already changed after setup

• I used a yum repository from IUS Community, especially for PHP and MySQL as well

• I have 2 dedicated ip (199.195.2XX.XXX and 199.195.3XX.XXX as example) from hosting provider

• I use a CMS website (which is WordPress) as filling a contact form whether i received or not

Well, to the point. After i setup a Virtualmin with ip 199.195.2XX.XXX, i click "Create Virtual Server" for adding my domain name. While i am creating virtual server and in section "IP address and forwarding", i add my dedicated ip 199.195.3XX.XXX in "Virtual with IP"

After that, i setup a DNS record for changing my MX records for Google Apps as email.

Now, when i am trying filling my contact form from my website and finished, i did not received to my email account right now.

And also, about backup in Virtualmin. After i click "Scheduled Backups", then click "Add a new backup schedule". While i setting my schedule backup and in section "Schedule and reporting", i am filling my email address in "Email backup report to" and tick "Also send email to owners of backed-up servers". And also choose "Simple schedule : Daily (at midnight)" in "Scheduled backup time". Then click "Create Schedule" and finished. After waiting 24 hours, i did not received email backup file from my server.

Well, that's my problem. So, what should i do for solving this problem? Is this a problem about PHP or something? Should i try modify "Server Templates"? I already tweak setting something else but it did not solve my problem. So, i need a hint please. I appreciated it if someone can help me about this problem. I will wait reply from you.

And by the way, sorry if i put word "Google Apps" and "Wordpress" that is not related in this forum.

Thank you.
