Wordpress Mail problem

**Operating system: Debian
**OS version: 10

Hi there,

I’m facing a problem with my Wordpress-Site. When I register for example a new user and when an E-Mail gets delivered, there is still the old hostname inside. In the raw format it looks like this:

Return-Path: wpsite@vmi123456.contaboserver.net

When I use for example the Usermin to send out an E-Mail it looks like this:

Return-Path: myname@mysite.com

Anyone knows maybe where I can set-up the hostname there correctly?

Thanks a lot

Did you change your email in Wordpress? You have to verify the email when you change it in WP.
