Roundcube, Squirrel Mail, webmail
Roundcube/Squirrel Mail say: Connection to storage server failed.
Server Error: Could not connect to localhost4:143: php_network_getaddresses: getaddrinfo failed: System error
How can I fix this?
It appears they are having trouble connecting to IPv6 localhost.
My /etc/hosts file has:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
So in /etc/roundcubemail/config.inc.php I changed
$config['default_host'] = 'localhost';
$config['default_host'] = 'localhost4';
To make it connect to localhost4 with IPv4 and it worked
And to correct Squirrel Mail I added the following to /etc/squirrelmail/config_local.php
$imapServerAddress = 'localhost4';
$smtpServerAddress = 'localhost4';
