SpamSieve’s Data Files
SpamSieve stores its training data in the folder:
/Users/<username>/Library/Application Support/SpamSieve/
and it stores its preferences in the file:
/Users/<username>/Library/Preferences/com.c-command.SpamSieve.plist
You should back up both of these. (See the How can I open the Library folder? section for how to access them.)
Moving or Copying SpamSieve to Another Mac (or User Account)
To transfer SpamSieve’s data to another machine, first quit both copies of SpamSieve. Then copy the folder and the preferences file to the corresponding locations on the other machine.
Your SpamSieve license will be transferred when you copy the preferences file. You can also transfer it manually, by looking up your order information.
When copying your SpamSieve setup to a Mac that didn’t previously have SpamSieve installed, you’ll need to put the SpamSieve application file in the Applications folder and do the setup in your mail program, but you can skip the initial training process because of the files that you copied above.
If you are copying the training data because you want to use SpamSieve on both Macs (rather than just moving it from one to the other), please see the SpamSieve and Multiple Macs section.
