Google Apps - Can't receive mail from a web form

Hi there, I have a website with a contact form working fine (ASP language, microsoft server). But since we signed with Google Apps to use MX records from Google, it is not working as it should. We send and receive emails normally using gmail webmail, but all emails that are originated from our website (contact form, automatically emails) are not working with gmail webmail. Reason seems to be related with "When someone submits the form on your website, the mail agent recognizes your domain name and concludes that it should be sending mail to itself. The mail agent will attempt to deliver the message locally." So we receive those emails only with Outlook (our previous email software). What I need is to change script on our website to work with Google Apps. I want to receive all emails originated from this website on our gmail webmail. This issue seemsrelated to this help topic: [login to view URL] Follow attached my actuall code using "[login to view URL]". I tryed to change it by using smtp from gmail, but it didn't work. Please send your offer only if you are confident to solve this issue. Thanks!
