I would love it if the Content Filter had the ability to strip specific attachments and then move to the next rule. For example we currently block XLSM (excel w/macro) files. In the current setup content filter just flat deletes the email. It would be nice to allow the email through after stripping the file. That way the end user at least knows there was an attempt and if needed to reach out to the sender to re-send with a different file type.
