I have a server with windows small business server 2003 SP2 installed with Exchange 2003 SP2. I use pop3 to download messages from the server from my email provider which is then routed to the user's mailbox. I send messages using the smtp connector which also has a smarthost configured. We use Sophos antivirus and sophos puremessage for spam.
I am able to send messages from and users email account from outlook 2003 to any external or internal user without any problems. I can receive message downloaded by the pop3connector and routed to the users mailbox without any problems.
However, I have when i set the out of office on the external user doe not receive the out of office message. I have had a look in the message tracking in ESM and can see a reply to the user with the out of office but when i open the message from message trcking it shows that it has got as far as - SMTP: Message submitted to categorizer.
I have stopped all sophos services and all smtp settings look fine and it is still doing the same thing. I have also restarted the exchange routing service and the SMtp service but still no joy.
Is there anything else i can check to get this working?
