The group settings effect sent mails if the user authenticates with the server, otherwise the default mail sending size is used (a mail size restriction within the general settings which affects all mails). The content filters unfortunatly cannot have restrictions based on groups, but you can of course do a domain wide block by usign the content filter "SMTP Sender Matches", with a "String Contains" and text of "@targetdomain.com".
