I run Exim with Hosting Controller. It's a Windows and Linux panel.
I want to enable authentication. Well, nothing new. I gather.
But HC creates userpasswords in special virtual files in /etc/vmail/.
So it creates /etc/vmail/shadow.mydomain.com, and:
/etc/vmail/passwd.mydomain.com.
But they do not work on Exim 4.69. I have two problems:
a) $domain in the string {/etc/vmail/passwd.@domain [2]} does not expand.
b) I can not get the permissions right.
The directory and files in /etc/vmail have root:mail and exim runs as:
Debian-exim:Debian-exim.
I added user Debian-exim to the group mail, but that does not seem to
work.
