Windows Server 2008 64bit Edition SMTP service logging
In Windows Server 2008 64bit edition, SMTP service isn't log even if you enabled the logging. It is found that you need to install the ODBC Logging module.
- Install ODBC Logging module (Server Manager > Roles > Web Server (IIS) > Add Role Services > Health and Diagnostics > ODBC Logging)
- Stop / Start the SMTP Service
- Verify your SMTP service is configured for logging. It's not on by default.
- Try a local telnet test (assuming the telnet client is installed)
- Look at your log folder.
