Receiving e-mails on behalf of

[nicky-lopes]

Hello,

I configured the postal and everything is OK but I'm receiving e-mails on my Outlook like this:

The e-mails are coming "on behalf of" and the sender is the return path (rp.domain.com.br)

how and where can I configure this the receive those e-mails without changing the sender?

I tried to unable to send from any sender like the post below but it didn't fix
#168 (comment)

Maybe something I missing.

thanks in advance!

how are you sending the messages?

[nicky-lopes]

I'm sending through Outlook using the SMTP user and key

[willpower232]

Postal is not designed for use with a desktop email client so that might explain it.

OK, but I got another server with an old version of the postal and when I configured to send an e-mail through the outlook I received with the e-mail sender and not "on behalf of".
Even when I try to send through API in a website it comes "on behalf of". I configured on the Outlook because its easier to make tests.

This is the header of the message that I receive from the new version:
I try to send with the domain.com.br but I receive rp.domain.com.br on behalf of domain.com.br

The only difference is that the new server is adding this lines

X-Sender: bcu2wz@rp.domain.com.br
Sender: bcu2wz@rp.domain.com.br
X-Envelope-From: bcu2wz@rp.domain.com.br

[nicky-lopes]

We identified that our e-mail provisor might be adding this lines when we send an e-mail thought the new server.
I'll talk to them first, and if it's not a problem with them I will come back later.

Thanks for to help.
