title: Mailbox on different server, domain on my server. Windows 2008 server
body: <p>I have one domain on my server and a mailbox (with the same domain ending) on a different server. I configured the mail and MX fields of DNS of that server to the proper value. All is working. But as I send an email from the website contact form (configured with SMTP = localhost) sending an email to the email address on the other server, the email will not reach the mail box ..Even no error is generated..Simply the mail server receives nothing. On the other hand from the contact form I can send email to different mailboxes.
  How to solve this ?</p>
