Hi Gail,

[Nice to hear from you!]

The admin assistant use case still requires an LDAP verification
of the target.  Deploying a printer without this (even one that
does NOT accept jobs from outside the enterprise) makes it a 
potential spam engine.

The IETF ADs were right to complain about this.  No printer
vendor wants to figure prominently in the next CERT alert for
security problems.

I also think the admin assistant use case is a corner case.  It's
not what existing LPR email notifications do in the UNIX space
(they reply to the job owner).

Cheers,
- Ira

Hi Ira,

I believe that one of the design points was to allow notifications to be
sent to a third party. The use case that was thrown around was the
ability of the notification to be sent to an administrative assistant to
be picked up.

Hi,

Note that our IETF ADs observed that there are serious security
flaws in the 'mailto' Delivery Method for IPP Notifications.
These will need to be addressed in any PWG-ISTO standard.

Simplified explanation:  An IPP Printer MUST NOT accept any
subscription for 'mailto' notifications from an anonymous
IPP Job submitter - otherwise, the IPP Printer is a spam 
engine.  An IPP Printer SHOULD use an LDAP directory (or 
other authoritative source) to ensure that the recipient
of IPP 'mailto' notifications is in fact the Job Owner.

Cheers,
- Ira

Yes.

The CUPS implementation will be ready for testing very soon, based
on the last draft.
