How can end users easily update Spamasssin?

[AlexPayne]

Do users have to log in to the control panel and then find the train spamassassin area or is there a simpler way through eg Horde (webmail)?

New to Plesk so want to get all the kinks and questions worked out before migrating users from our Cobalts......Thanks in advance.

When they use the webmail interface they can tag mails as spam.
You as admin can add addresses to a global black- or white list and define the spam level for each domain or the server in general.
