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 ?
