Spamassassin error even without Spamassassin

[Stephen Lee]

I got the following error even with "Use SpamAssassin = no":

MailScanner[802]: You need to set the "SpamAssassin User State Dir" to a
directory that the "Run As User" can write to.

I simply pointed it to "/tmp" and that got rid of the message. Do I need
to turn off SA somewhere else in the configs?

My box runs RH7.3/MS-4.20-3RPM.

Thanks,
Stephen
