We're unable to find your webserver.  We support Apache and Nginx

Do you wish to install a webserver?
1 - Apache

Found the problem: PHP7.0 has libapache2-mod-php7.0 as dependency if php7.0-fpm and php7.0-cgi are not beeing installed: https://packages.debian.org/stretch/php7.0

[Skywalker-11]

Can you try #26? It should fix the problem. Nevertheless until now I have't tested nginx installation at all 😄

[endelwar]

Going to test in a couple of hours, also I'm going to prepare a basic nginx config file.

Should we continue with "/mailscanner" dir alias or move to the more modern "mailwatch.example.com" virtual domain in install script?

[endelwar]

I finally managed to test #26 and I can confirm that it works on debian 9 and debian 8.

I'm trying to create a base nginx config file, but nginx doesn't have a global alias like apache (Alias /mailwatch/ "WEBFOLDER"), aliases must reside inside a location directive, which must reside inside a server directive: in nginx every site definition is equivalent to a virtualhost, even the default catchall site (server_name _;).

I can take 2 way:

• create a mailwatch.example.com virtualhost config and put it in /etc/nginx/sites-available
• modify /etc/nginx/sites-available/default adding a location /mailwatch/ directive

Should we sync this between nginx and apache?

[Skywalker-11]

Im that case it is probably better to just use a virtualhost for both apache and nginx.
