Log files are an important aspect of any mail server. You need to understand what the various log files that MailEnable produces in order to find and rectify any problem. Fortunately, MailEnable can produce a large amount of logging information to help you isolate a problem.
MailEnable usually can produce 3 logs for each service. The are called W3C, Activity and Debug logs. The W3C log has all the information about what is passing to and from the mail server in W3C extended log file format ( www.w3c.org). The Activity log will display all the information that is passing to and from the server. The Debug log is used to display information about what the service is actually doing.
When you first think you are having a problem with email, there are some quick steps to resolve the problem, which basically involve examining the various log files. If you follow the guidelines below to see which log file will help you, issues will get resolved faster.
Check the Debug log file first. This will more likely have information about the error that the service has encountered. The Debug log will show errors such as DNS failures, file errors, send problems, etc.
If you cannot see the issue in the Debug log, it is likely that it is not a program error, but an error in conversation between the servers (i.e. the server may be trying a command that isn't supported).
