we'll check

Hello @saunders, I checked the code and there is $baseurl is used for the url from your screenshot.
The default text in English version is "This message was automatically generated by b2evolution running on This site.".
I guess on your site "This site" = "fokus genba" and $baseurl = https://www.genba.org/blogs/, if yes please try to change it to https://fokus.genba.org/.
Thanks.

@yurabakhtin in my b2e instance i have several collections and each referring to another subdomain, and additional there is a collection not using a subdomain. So a baseurl with fokus.genba.org would only shift the problem to elsewhere but would not solve it.

@saunders Changing this message is not currently supported. It is a single contact point. If you need separate emailing (and/or separate user accounts) for your sites, you need to install several versions of b2evolution.

Possible hack: make a custom footer template and remove this line.

We might support multiple email bases in the future but we have limited developer resources and need to make some prioritization choices.

@fplanque so I do have to wait for future features to get a fully multidomain platform.
Meanwhile I will try adapt the footer of the Message (thanks for that hint)
