Good morning, I've been trying to troubleshoot why Mailgraph is not working on my fresh install of Debian 9. What I've done: - Installed the software packages via the Perfect Setup (https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/). - Setup website with CGI and SuEXEC both checked. - Installed mailgraph using apt-get (essentially followed these steps: https://www.howtoforge.com/postfix-monitoring-with-mailgraph-and-pflogsumm-on-debian-lenny) - Moved mailgraph.cgi to the cgi-bin folder and changed ownership to match the site. * I did however learn that the default location has changed. (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865914) When I visit: www.mydomain.com/cgi-bin/mailgraph.cgi I get the HTML served with no graphs displayed. It appears as if the images are not being created in the temp directory in /var/lib/mailgraph. When I disable SuEXEC in the web interface and wait ~5 minutes I can reload the mailgraph.cgi and everything is displayed correctly. From what I can tell it is a permissions issue but not sure where it is: ISPConfig, SuExec, or mailgraph's install. There are no errors in suexec.log or access.log for apache2. Any troubleshooting thoughts would be appreciated.
