Theo,
In the user's .procmailrc file, there is this stanza:
:0fw: spamassassin.lock
| /usr/bin/spamc -u username -s 128000
But, I have had this problem occur arbitrarily when no -u username is
specified. I think by the time Exim4 gets to the .procmailrc, it has
already dropped privileges, so spamc would get called as that user from
the user's .procmailrc file. But regardless, sometimes spamd can drop
privileges, and sometimes it can't... a ratio of about 1:400 for
can't/can. So, I'm not sure if that indicates some sort of problem
external to spamd or not? I've seen other reports of this around, but
no solutions. Hope this extra information helps, let me know if you
need any additional info!
A failure of your system's auth backend could cause this. Are you using
something other than flat file /etc/passwd and /etc/group?
