Thanks for the tip.  I found 4.34 on the download site, but the main 
Exim page still says that 4.32 is the latest version - is the Exim home 
page wrong, or is 4.34 a pre-release version?

I'm using Mac OS X, and a year or so ago when I tried to use the 
SA-Exim dynamic module, it wouldn't work.  I seem to remember there was 
a library missing, and Marc said that Mac OS X didn't appear to support 
dynamic modules yet.  I don't remember the details.  I'll try it again 
after I get this problem fixed.

The same exact lines appear in both the mainlog and the rejectlog, but 
nothing relevant appears in the paniclog:

# grep HXP86L-000KXM-2Y mainlog rejectlog paniclog
mainlog:2004-05-14 06:08:58 HXP86L-000KXM-2Y local_scan() function 
crashed with signal 11 - message temporarily rejected (size 2402302)

Sending a large message to myself also fails in the same way with 
local_scan() crashing.  I'm using the latest releases of SpamAssassin 
and SA-Exim, and what I thought was the latest release of Exim; I could 
move to the pre-release SpamAssassin 3.0, but I'd rather not be on the 
bleeding edge.

> Tried running spamc by hand on a very large file?

That just sends the file back to me via stdout.  If I give spamc the -R 
option, it reports "0/0", which I believe means an error occurred, but 
I think this is because I don't know the right format of the message to 
feed to spamc.  At any rate, spamc isn't crashing.

Not yet, but I'll give that a try.  Thanks for the tips.
