Exists a size restriction for the delivery of mails?

By using the object type "Distribution list", attention should be paid to the size of content and attachments.

Content Maximum size in MB (content and attachments)
More than 100 recipients 5
More than 1000 recipients 1

If the size restriction is achieved or exeeded, the sender is automatically informed via mail after pressing the button "Send". In this case, the mail to the "Distribution list" is not sent.
