Allow Roundcube to connect to IMAP server

[stijneikelboom]

Is your feature request related to a problem? Please describe.
After the conversion, it is impossible to log in to Roundcube Webmail. The error indicates that the connection to the IMAP server failed.

It turns out this is because SELinux is blocking outbound network connections from httpd.

Describe the solution you'd like
Set the httpd_can_network_connect boolean to True during the conversion, or apply a more specific policy change if feasible.

Describe alternatives you've considered
Manually change the SELinux boolean after the conversion.

setsebool -P httpd_can_network_connect 1

From what I understand, httpd_can_network_connect is true by default. So, it is usually changed manually.
I would prefer not to alter any SELinux settings manually changed before conversion process, because this might be unexpected for the administrator and could affect the security policy
However, we could add a pre-check to the conversion process. This pre-check would verify if httpd_can_network_connect is true. If it is not, a warning message could be displayed to the user.
