[lug] Mozilla mail client misses messages?

[Bear Giles]

I just discovered something rather shocking while coding an 
embedded Java mail client.  According to Mozilla 1.5, my inbox has 
699 messages.  According to the Java client, it had over 800 
messages.  When I check the mail spool directly (one of the 
benefits of running your own mail server) I found over 800 
individual messages.

Back in Mozilla, my inbox is fairly clean after the morning purge 
of the spam that got through spamassassin.  The subject lines in 
the Java mail client look like a drunk frat party minutes before 
the police arrive.

I've manually purged a fair amount of the crap, but the Mozilla 
message count is unchanged.  It's like Mozilla and my other client 
are seeing entirely different mail spools, but I know that's not 
the case.

Has anyone else seen this behavior?
