I am trying to install roundcube.
If the server name is server.abc.com and I leave the following blank: $rcmail_config['smtp_server'] = '';
... then email is sent as: user@server.abc.com
But I need email to be sent as user@abc.com
So if I change the following as such: $rcmail_config['smtp_server'] = 'abc.com';
... then when I send I get the error: SMTP Error (-1): Connection to server failed.
How can I send as abc.com ?
