That all depends on how your host has setup that part of the server. WordPress sends my emails from wordpress@mydomain.com as root@mydomain.com .
I am getting the very same problem. Is there anything that can be done within the programs configuration or do I simply need to speak to my ISP to configure this for me?
I want users to receive an email from administrator@myisp.com. If I do need my ISP to resolve this for me, what exactly (technically) am I asking them to do?
The setting which uses the server name is set during initial install by install.php. Has anyone discovered a way to change the setting after installation?
Apparently this topic was never resolved…
Users signing up get an email from “myusername@box142.hosting.com”. How can I replace that with name@mywebsite.com?
Following macmanx’s advise I contacted my hosting company. They sent me this unhelpfull reply:
You will need to modify the script (usually a configuration script) so that it uses your e-mail address sends the e-mail from myname@mywebsite.com
So which script should I modify how?
