[SA-exim] spamc unable to connect to spamd

[Hess, M.Todd, /mth]

Occasionally, spamc reports that it can't connect to spamd: 

      "connect() to spamd failed: Connection refused"  

I have not been able to figure out why this happens.  When this happens,
email bypasses the spamd and continues to be delivered.  

Until I can solve this problem, I would like the email to be held until
spamc is able to connect to spamd again.  Is there a way I can force spamc
to wait "forever" for a spamd connection?  I read about the "-f" flag, but
that won't accomplish what I need.

TIA!
