The frevvo mail server limits email size to 30MB. If emails sent in Activity Doc Action or Document Actions exceed this limit, your tenant admin may receive an email bounceback from "Mail Delivery System <"MAILER-DAEMON@sysops+stage"@frevvo.com>" that contains error like this "message size 34559092 exceeds size limit 31457280 of server smtp.sendgrid.net[22.214.171.124]".
The only workaround for this issue at this time except is to limit the upload Upload control max size and/or min # properties in your form. If you have a submission that has hit this error, you must edit the submission, delete some of the attachments and then resubmit.
