I am having a problem with sending mails.
I have 2 domains.
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 :)
