Hello Mark,
You will want to look on the machine for this issue as the connection to the mail server was never made. With no connection nothin will be in the SmarterMail logs.
Things that can be tested on why the server was unreachable.
- can the server be pinged
- can a telnet to the correct port be made with a 200 response
- openssl for secure connections ( 465, 25/587 with STARTTLS )
- anything in Outlooks advanced logging?
For these tests to work they will need to be performed during the issue from the clients machine.
Other possible options as well.
- flush dns on the local machine
- try starting outlook in safe mode.
- check traffic on your firewall
