Once the automatic import is activated, each new incoming mail should come up as a new file in a mailfile directory. It is created with a .received suffix, which gets renamed to .processed as soon as manitou-mdx has imported it into the database. manitou-mdx will check periodically for new files in these directories.
It is also possible to monitor via the
runtime_info table of the database. See the
alive_interval parameter in the configuration file.
