Forget Password Mailing Error

[Karl_T]

 Hello everyone! I am a newbie and I am trying to use the forget password button on the login page.

Before that, I added a random email for testing like this one "KerryOki@InboxProxy.com" in my admin setting area.

After submitting the user name "admin" , an error message occur:

WireMail: Invalid email address (processwire@localhost)

and no email has been received.

I tried to install an extension mailing module WireMailSmtp, same error occur:

WireMailSmtp: Invalid email address (processwire@localhost)

processwire@localhost is not what I have input. I used KerryOki@InboxProxy.com.

I tried using other users, but same error occur. How can I fix it?

I cannot google similar issue, please forgive me if I make repeated topic.  Thanks in advance!
