You could try to telnet to port 41025 (assuming default configuration) which is the receiving port for email to get put into the spam quarantine.
If you can connect on that port, then maybe do an ad-hoc SMTP conversation to ensure you can inject mail into the quarantine.
(this will confirm the quarantine can accept mail)
The other thing is to double check that your non-local relay host is properly configured. If the quarantine processor can't access THAT host, mail will just accumulate in the quarantine until it expires and the expunger deletes it.
(this will confirm the quarantine can offload/deliver mail)
One other idea is that maybe the quarantine isn't the primary issue: that "internal" message may be an indication that the filtering component is crashing. As Isha pointed out: are you seeing backup in the inbound, outbound, or delivery queues? If they are in the inbound or outbound queues, it is more likely that the filtering component is crashing and re-starting.
Normal flow is inbound or outbound acceptance -> filtering component -> delivery queue -> off to the next hop/destination.
Alternate flow is inbound/outbound acceptance -> filtering component -> quarantine -> quarantine release host -> off to the next hop/destination.
While you are at it, might as well check the "bad message" queue: sometimes you get some aberrant email that sucks up resources in the filtering layer, fails, gets re-submitted for filtering, gumming up the works. If we detect this internally, we will sideline that email in the bad messages queue indefinitely.

Any solutions?
