For end-user changes to spamassassin which config file is the correct one to modify? I've seen a variety of answers and want to make sure it is the correct one in 8.0.4:

/opt/zimbra/conf/sa/salocal.cf
/opt/zimbra/conf/salocal.cf.in
/opt/zimbra/conf/spamassassin/local.cf

Or some other one?

Thanks in advance!
