how to increase sending email limit per 24 hours

hi,
i want to send bulk emails to the record users,but what i could send only 250 emial and after this it gives me the error:Error:The following From address failed: knarula@kineticxtech.com : MAIL FROM command failed,User has exceeded its 24-hour sending limit. Messages to 259 recipients out of 250 allowed have been sent. Relay quota will reset in 1.16 hours. ,550,SMTP server error: MAIL FROM command failed Detail: User has exceeded its 24-hour sending limit. Messages to 259 recipients out of 250 allowed have been sent. Relay quota will reset in 1.16 hours. SMTP code: 550SMTP server error: MAIL FROM command failed Detail: User has exceeded its 24-hour sending limit. Messages to 259 recipients out of 250 allowed have been sent. Relay quota will reset in 1.16 hours. SMTP code: 550.
i have changed in config_override.php file online $sugar_config[‘email_sugarclient_listviewmaxselect’] = 1000;
but it is getting stopped at the limit of 250.
please suggest how it would be correct.

Thanks & Regards

this is a limit in your mail server, has nothing to do with SuiteCRM, contact your mail host provider

best regards

Thank you so much mikebeck
