Another person asked a similar question recently, and the answer is a
bit complicated.  spamass-milter doesn't know what user database
spamassassin has available to it, so all its -u flag can do is extract
the recipient name and pass it on.  If there are multiple recipients,
the username is whatever the -u argument was set to.

When spamassassin gets hold of the message, is tries to look up the
username passed from spamass-milter.  If that fails, it simply uses the
default settings.  The spamd logs may claim that's it's using the
settings for "nobody", but it isn't.  So as long as you have reasonable
default settings in your local.cf, everything should work.
