Throttling mailings to comply with hosting restrictions
Many hosting companies put a limit on how many e-mails you can send out per hour. If you exceed this total then your hosting company will bounce all your e-mails and it rapidly becomes impossible to manage your system.
How to do it…
CiviCRM can set limits to how many mailings are sent out per hour.
Navigate to Administer | System Settings | Scheduled Jobs and make sure that the Mailings Scheduler option is set to run at hourly intervals.
Navigate to Administer | CiviMail | Mail settings.
Configure the Mailer Batch Limit option to a figure slightly below the hourly limit allowed by your hosting provider.
