[Mimedefang] quarantine confusion

[cc]

Hi,

Can someone please point out whether the following is the
correct way of approaching attachments?

  I'd like to quarantine all incoming messages that
contain attachments.  Once quarantined, another message is
sent to the actual recipient of the fact that the message
was quarantined and to view the message (retrieve it), the
user has to respond by clicking on Reply (the subject
might have some randomly generated code which matches
the quarantined message.  Once received, mimedefang
then resends the quarantined message to the intended
user.   After a day or so, the left over quarantined
messages are deleted (or forwarded to the user defang
for further inspection).

Is this a little too much?

Another idea is to rename the attachment(s) to
a different serial name, but still send the message
to the user stating at the top that the attachments
were renamed.  And also include a list of the
original attachment names and to what they were
renamed to.

Are any of these ideas do-able in mimedefang?
I haven't set up an AV yet, so this is the
only way I can think of to prevent users
accidentally running the said attachments.

Any help appreciated.
