SBS 2003 outbound email not flowing to some domains/addresses
Posted on 2011-02-22
I have a SBS 2003 server that uses mxlogic inbound and outbound service that is having difficulty sending email. Over the weekend the server was restarted and shortly after that users recieved NDR for email they had sent on Feb 9, 2011. That day the server was restarted at about 1:00 am. It seems some email was not delivered during that time, but no delayed reports were given. The server is set to give delay notifications after 2 hours and failure reports after 2 days. When I started checking things this morning, I saw no sign of proplems: nothing in the queues and no failed send attempts in the logs. But test messages that the users have sent out this morning to various clients/contacts, have not be received. However, some outbound messages are going out. But these test messages are not listed in the queues anywhere. Where are these messages, that have been sent from Outlook, not sent through the SMTP server, but not appearing in the logs?
Server is running TrendMicro Worry-Free Business advanced, but just noticed that the license expired on Jan 27, 2011, but they still have 4 days left in the grace period. Realtime monitor shows current email activity, but no viruses/spam...
