Configuring deferred message delivery
You can choose to defer delivery of two types of email to conserve bandwidth and improve performance of the mail server:
• large email messages
• lower priority email from certain senders, for example, marketing campaign email and mass mailing
Oversized message delivery can be resource-intensive. For improved FortiMail performance, schedule delivery during times when email traffic volume is low, such as nights and weekends.
To set a deferral period, configure both of the following:
• In Start delivering messages at, select the hour and minute of the day at which to begin delivering oversize email messages.
• In Stop delivering messages at, select the hour and minute of the day at which to stop delivering oversize email messages.
To configure the size limit or senders of deferred email, see
“Configuring content profiles”.
