Hi Mungatsia,

I don't know the guidelines off the top of my head for Exchange. However, I suppose you can gugu for clues.
For example this one: http://technet.microsoft.com/en-us/library/bb430765(v=exchg.150).aspx

And this elaborate one: http://www.computerperformance.co.uk/exchange2010/exchange_2010_ndr.htm

Pardon me since I don't know if what applies to Exchange 2013 will also apply to 2010. However, as admins, you should be knowing.

Hi Washington,

Thanks, that's the same message we got from AK. Kindly send us the guideline on how we can change the oof notifications to use the postmaster address.

FYI - Access Kenya SMTP Servers reject the null sender. I have tried to convince the guys to change this, but hit a dead wall. It's just one negative opinion I hold against AK - rfc-ignorant admins.
If you are using AK as a smart host, you better arrange to send out OoO notifications using postmaster@your.dom.ain

Hi Geoffrey,

I have been working with Charles trying to troubleshoot this issue. Since you have said yours works perfectly for external users then just kindly confirm to us the following:

are you using a smart host?
Which ISP?
patch level for your exchange 2010?

Thanx.

then check your transport rules , those are the only ones that can change sender info, i dont quite understand what you mean by "In Exchange 2010/2007 Microsoft has changed the behavior of automatic server based notifications, especially “Out of Office” replies which should be sent with a blank sender This means that the HUB Server in your organization replaces the senders name with a blank one while transferring it to the internet."  this doesn't sound normal... mine works fine and doesn't change anything is the sender info

Hello Friends; 

I Have Exchange 2010 Server running in Windows Server 2008. My problem are as follows:
- Out Of Office Messages are only sent internally and NOT externally .
- After researching i realised that  Out of Office messages are being rejected due to the null <> used as sender  . In Exchange 2010/2007 Microsoft has changed the behavior of automatic server based notifications, especially “Out of Office” replies which should be sent with a blank sender This means that the HUB Server in your organization replaces the senders name with a blank one while transferring it to the internet.


Facts : 
- I have no firewall installed for incoming/outgoing emails hence you can overlook this. 
- Exchange Connectivity test results are ok . 
- If you create an Open Relay Send connector the Out Of Office Message is sent to external clients but we receive very many NDrs  since most Smart Hosts reject messages from a n Open Relay Send Connector. 
- The Companies Smart Host is smtpout.accesskenya.com 
- CMD Shell Results  : 

All our settings are correctly configured . Below are the CMD Shell  Results :

 

NonMimeCharacterSet                      : iso-8859-1
AllowedOOFType                               : External
AutoReplyEnabled                             : True
AutoForwardEnabled                        : True
DeliveryReportEnabled                     : True
NDREnabled                                      : True
MeetingForwardNotificationEnabled : False
ContentType                                      : MimeHtmlText
DisplaySenderName                           : True
TNEFEnabled                       :

Our CMD Results indicate that the message is configured .

Is there anyone who can help with this ?
