Yes, from experience, this is exactly what happens - exim just 45x's
messages until clamd is restarted.

spamc I think is responsible for this - it tries 3 times to contact
spamd, and if it can't, it just passes the message back. At least
that's the theory - I don't believe we've ever lost mail or 45x'ed it
when spamd keeled over, at any rate.
