Allow different authenticated address / from address ?
Question asked by Rafael Grecco - April 29, 2015 at 5:32 AM

Hi,
 
I have a costumer which uses his ERP system to send e-mails through my Smartermail server.
 
He has configured a default account for his system, so all e-mails are sent from erp@example.com.
 
But this system uses the user's address as the sending address, so the e-mail must be sent using one e-mail address (erp@example.com) but using the logged user's e-mail address as "from address"(john@example.com).
 
When this happens they get this error: "550 from address must match authenticated address" and the e-mail is not sent.
 
I have three questions:
 
1. I don't remember changing anything on my server configuration, but my costumer says that his ERP has always worked this way and he started getting this error recently. I have not upgraded Smartermail recently. What could have happened? (Maybe I changed some config but I don't remember...)
 
2. Is there a way to allow that behavior?
 
3. Is it dangerous to allow it? Is there any downside to it?
 
Thank you!!
Rafael

Hi Rafael,
 
There is a setting in SmarterMail that requires the authenticated email address to be the same as the from address.  This setting is found as the system admin under Settings | Protocol Settings | SMTP in tab and change the "Require Auth Match" to None.  Then your customer should be able to send out from there ERP as before.
