Minimize SMTP Recipient Quantity

The glide.email.smtp.max_recipients specifies the maximum number of recipients the instance can list in the To: line for a single email notification.

The glide.email.smtp.max_recipients system property specifies the maximum number of recipients the instance can list in the To: line for a single email notification. Notifications that would exceed this limit instead create duplicate email notifications addressed to a subset of the recipient list. Each email notification has the same maximum number of recipients.

Ensure that the property glide.email.smtp.max_recipients is set to 100 or less.
