Mail Extension – SendMessageWithNoReplyTo still sends from main account

Hi everyone,

I’m using the ThingWorx Mail Extension and the service SendMessageWithNoReplyTo.
Even though I set a No-Reply Address (e.g., donotreply@something.com), all outgoing emails are still being sent from the authenticated mail account instead of the no-reply address.

It looks like the SMTP server always overwrites the “From” address with the login user.
Has anyone found a way to make SendMessageWithNoReplyTo actually send from the No-Reply Address?
Or is this behavior controlled entirely by the mail server (e.g., requiring “Send As” permission)?

Thanks in advance for your help!

here is the documentation for mail extension of thingworx

My solution: I have requested an SMTP server in my company for my thingworx server with its ip address and they have issued me SMTP server and with that i even dont have to add my Mail account User and Mail account password and i can send email to anyone with no reply email address. Its working fine. Our goal was to send emails internally and its working.
