I installed Roundcube 1.4.1 on a sandbox server running CentOS 7, Postfix and
Dovecot, with half a dozen test email accounts.
Mail is setup correctly under the hood, e. g. I can access any account via
Thunderbird for sending and receiving mail.
And SELinux is set to permissive until everything works correctly.
I took some notes (in french) on the installation procedure under CentOS :
* https://github.com/kikinovak/HOWTOs/blob/master/Roundcube-HOWTO.txt
All tests in the installer (including SMTP and IMAP login) are OK.
But still, when I login to an account, no emails are showing. The inbox shows
up empty, even if it's not.
Another malfunction is that I cannot edit any identity. When I click on the
user's identity, I get a spinning wheel, and the page does not open.
I already have Roundcube 1.4rc1 running on my main workhorse server, it runs
nicely. I tried to figure out what I did differently on that machine, but
couldn't figure it out so far.
I took a peek in the various log files, but found nothing suspect. Or maybe I
don't know what to look for.
Any suggestions? I'm a bit clueless here and don't even know where to start.
I'll answer this myself, since I just found the culprit.
It turns out Roundcube uses iframes to display messages, which were blocked by
my Apache configuration.
I corrected this by adding the following option to my server configuration:
Header always set X-Frame-Options "SAMEORIGIN"
...
I suggest using Content-Security-Policy headers for that instead ...
