  • Question

  • Hello,

    We are a medium based company that is struggling with our IT company to set up the following.  Our company is AAA Energy.

    We have a company for the sake of this email we will call them "Not Our Company" that is going to be sending out forms on our behalf. They allow custom SMTP set up so that when our customers get the email it comes from our domain. 

    Example: Our employees fill out a digital form on their devise via "Not Our Company's" portal or app and enter in our clients email address for the form to be sent to.  Once they submit the form it is sent from the Not Our Company's server automatically. The from is coming in as donotreply @ notourcompany .com.  We are struggling to set up a relay or whatever it is that needs to happen so that it comes to our server first and changes the from to our domain.  We would like the email to come from donotreply @ aaaenergy .com.  We have the sender donotreply @ notourcompany .com does not have the ability to send on our behalf using our domain.  They offer the "use custom SMTP" and have other clients that are successfully implementing it.

    Unfortunately Not Our Company is unable to give much more that using port 25, whitelist IP addresses and a place for our user name and password for authentication. 

    Can you be of assistance on how to set this up?  Our IT company is struggling and we need help.  Please feel free to email me anything.  ceverett @ aaaenergy .com. 

    Thank you,

    Chad Everett

  • Hi,

    I would suggest to contact a consultancy company to assist you with the issue. It is very difficult to determine how it is setup without see the setup.

  • Hi,

    Thanks for contacting our forum.

    What’s the detailed Exchange versions and servers in your organization? Please run the following commands and have a check:

    Get-exchangeserver | fl name, *version*, *role*

    Get-acceptdomain  | fl

    Have you configured open relay on the receive connector of your exchange server?

    It’s recommended to read the address rewrite and check if this meet your requirements.

    Hope it helps.


    Regards,

    Jason Chao

  • Just have "Not Our Company" send the mail directly to the recipients using your company's e-mail address as the from address.  Before they do that, modify your Internet DNS SPF record so that their organization is listed in one of the methods, such as their sending IP address, as a valid sender on behalf of your domain so that their mailings aren't automatically triggered by the recipients as spam.
