Notes
To check the default webmail client that a user uses for their email box on a cPanel server, you can use the following command:
egrep "roundcube|horde" /home/*/.cpanel/nvdata/*_default_webmail_app
It will show a user, email box and default webmail app that set up by the user by default
Check the message_size_limit value
exim -bP | grep message_size_limit
message_size_limit = 50M
Increase if needed in
/etc/exim.conf Since recently: /etc/exim.conf.local
Rebuild and restart exim:
/scripts/buildeximconf service exim restart
If you’re still getting the problem please view the following explanation:
Mysql server and InnoDB engine must to be running!
Check mysql connection:
cat /usr/local/cpanel/base/3rdparty/roundcube/config/config.inc.php |grep mysql: $config['db_dsnw'] = 'mysql://roundcube:lasMubMX08D3HKtr@unix(/var/lib/mysql/mysql.sock)/roundcube';
mysql -u roundcube -p
show tables;
All tables should be in place:
+---------------------+ | Tables_in_roundcube | +---------------------+ | cache | | cache_index | | cache_messages | | cache_shared | | cache_thread | | contactgroupmembers | | contactgroups | | contacts | | cp_schema_version | | dictionary | | identities | | searches | | session | | system | | users | +---------------------+ 15 rows in set (0.00 sec)
Cpanel keeps roundcube backups here:
