Currently our session size limit in the default SMTP server is 100MB. We set this as users need to scan large documents into their email. We currently don't have a message size set.
As a result, if a user sends a large email to a large number of users, our Exchange server grinds to a halt as we perform archiving as well.
Is there a way to set the message size from users as 10MB and the message size from scanners as 100MB?
