Squirrelmail was driving me crazy – incoming email filtering (via avelsieve) was broken in the old stuff, and the preview pane is broken in the new. Nothing seems to be very actively maintained. So I revisited Roundcube, and it looks good.
I’ll be keeping Squirrelmail around to manage my incoming email filtering – avelsieve is just really nice to work with – and I’ll be using Roundcube for my web client. And Thunderbird works great when no corporate firewall is in the way. Works for me…
The only changes I made during Roundcube setup were within [config/db.inc.php] (trivial) and [config/main.inc.php]:
// MDM I used this to install, then moved the installer directory to backup...
// $rcmail_config['enable_installer'] = true;
// MDM This prevents the silly "host" box on login.
// Don't use 'localhost' or outgoing email will fail!
$rcmail_config['default_host'] = 'myserver.com';
