I have the same problem!
I recently installed sqwebmail 3.6.0 and I can't get the login page. In order to be able to open the login page, it's necessary to set a ScriptAlias in httpd.conf and specify the path to the sqwebmail binary, like this:
ScriptAlias /cgi-bin/ /var/www/cgi-bin/
Allow from all
These are lines from my httpd.conf
The sqwebmail binary file is in /var/www/cgi-bin and both the directory and the file have 777 permissions, but when I open a browser and type http://mydomain/cgi-bin/
I get a no permission error from apache!
Watching the apache logs I found this:
[Wed Sep 17 12:50:28 2003] [error] [client 10.0.0.1] client denied by server configuration: /var/www/cgi-bin
What could be wrong if everything seems OK?
