email issue comments - can we keep them "internal" only?

[Rich Ollari]

Jira SD supports the ability to have issue comments updated simply by sending emailing to our support@ email address with the ticket # in the subject line.  This feature has saved use a great deal of time and effort.  We're wondering if these added comments can be designated as "internal" only so the end customer will not be notified of the comment?  

Thanks in advance!
