Christian's questions

In a Exchange 2003 the SMTP collector has the 'Delivery Restriction' configurated to deny for all except for who is in a security group mail-enabled (called 'InternetMail').

There are user mail-enabled and dummy user for shared mailbox ( think them as 'office mailbox' delegated to many users )

Some user mail-enabled and some dummy-user mail-enabled are in the InternetMail group and other no.

So far so good.

The issue is that when a user with personal mailbox is in the InternetMail group and has also access to a dummy mailbox (not in the InternetMail group) can send emails outside also from this dummy mailbox even if it is not in the group!

My guess is that the 'delivery restriction' lookup, not only look to the group-membership of the user owner of the mailbox, but also, the group-membership of the delegated user with 'send as' permission to evaluate the condition.

Maybe is by design but I need some microsoft document to certificate this behaviour or the evidence that something is not right configured in exchange. I've try a deep googling but no luck, maybe I've wrong the query...

Feel free to ask more information or clarificaton.

In a default Exchange 2010 installation when a user account is disabled there is an automatism, in exchange, that delete or disconnect the mailbox associated to the user?

If yes, how this behaviour can be modified?

In a windows 2003 DC (with DNS role) I need to remove a 2nd ip (added many years ago by precedent sysadmin and no one know why!) on a single NIC. This because the domain have a new trust with an other domain and we have many connections issues with applications.

Someone Know if is needed a reboot for having changes to take effect? The DNS will update the entry automatically?

In a Windows 2003 domain, I have 7 members servers that are Windows Server 2008 R2. I need to make it so that they sync time with the PDC emulator at least every 15 minutes or less if possible. Is this possible?
