Question Plesk Premuim Mail - where do I have to transfer SPAM mails to teach the SPAM filter

[onki]

Hi,

AFAIK Premium mail is using Spamassasin as SPAM filter.
This comes with a capability to learn from user defined SPAM mails, that are moved to a specific mail folder.
When I look at my folder list I can find a folder called /SPAM and another one is called /SPAMBOX.
There is also a folder inbox/SPAM. This is most likely due to the other mail software that has been used before.
Which one is correct or can I specify the folder in a configuration file?

Best regards
Onki
