Yes, certainly.  Thanks for responding.

I must respectfully disagree, as I have been using it since its posting.

Creating a user and choosing "None (no mailbox. Just forwardings)" for the "Create mailbox on server" also results in a mailLocalAddress being generated but no mailRoutingAddress.

Would not the same thing happen if you created a user without a mailbox and failed to set any forwarding addresses?

The point of the patch is to handle the case where a user wants his mail forwarded, and no longer wants it to also be delivered to our system.  The resulting LDAP data is identical to a "None (no mailbox. Just forwardings)" user except that mailHost is still set, allowing mailRoutingAddress to be regenerated and the existing (but inactive) mailbox to be identified.

But I do not want to disable mail for the user, only mailbox delivery.

A more thorough patch might go so far as to delete the mailbox (and remove the mailHost attribute), but I was a little squeamish about deleting mailboxes, and some users want a period of time to move their mail from our mailbox to their forwarded mailbox.
