Uwagi

Database Mail messages and their attachments are stored in the msdb database. Messages should be periodically deleted to prevent msdb from growing larger than expected and to comply with your organizations document retention program. Use the sysmail_delete_mailitems_sp stored procedure to permanently delete e-mail messages from the Database Mail tables. An optional argument allows you to delete only older e-mails by providing a date and time. E-mails older than that argument will be deleted. Another optional argument allows you to delete only e-mails of a certain type, specified as the sent_status argument. You must provide an argument either for @sent_before or @sent_status. To delete all messages, use @sent_before = getdate().

Deleting e-mail also deletes attachments related to those messages. Deleting e-mail does not delete the corresponding entries in sysmail_event_log. Use sysmail_delete_log_sp to delete items from the log.

Permissions

Members of the sysadmin fixed server role can execute this procedure to delete e-mails sent by all users. Members of DatabaseMailUserRole can only delete e-mails sent by that user.
