Problem with sending mails with SMTP and Web-site Form

Hello,

I am having a problem with sending mails.

I have 2 domains.
1. vistasign.com
2. vistasystem.com

Vistasign.com is our org in Israel and Vistasystem.com is our cloud in USA.

In Vistasign.com I have SMTP server running on Windows 2008 R2.

Now, our webmaster made a code that every forms our clients send it will send him an email with the results.

Now, we are testing the system and when we try to send mails from @Vistasign.com it works fine and when we send mails from @Vistasystem.com it works fine also, we recevice the mails.

Now, we have also an ESMTP server sitting on Windows Server 2008 R2 @ our cloud, which use the domain Vistasystem.com

When the web-master using the ESMTP server from Vistasystem.com it works only if we send mails from @Vistasign.com ONLY. when we try to send mails from @Vistasystem.com we doesn’t receive it at all.

I’ve tried also to telnet it, and it works fine. when I use TELNET EHLO RCPT TO MAIL FROM I receive the mails from @Vistasystem.com but when we use the web-site it doesn’t (the .NET doesn’t give us any relay error or anything wrong).

Can anybody advice me what can we do please?

Thank you so much :)
