From the Maintenance app go to "Settings">"Equipment Categories".
Create a new category, insert a name and save. An alias get
automatically created with the same name as the new category.
The new alias point to "Maintenance Equipment" model, so when
an email is matched with the alias a new equipment under the new category
is created. This is indeed the default behavior but the help message
is deceiving the user. Changing it.
