I'm sure I must. I just don't know where.

I always read the docs before I try asking dumb questions ;)

That's why you don't see me on the list much.

I do.

I thought so, since it's pretty much copied directly out of the docs.

The normal way, with an smtp connection.

Exim runs as user mail...I thought having the clamav user in the mail
group would be sufficient, but I changed this to "User mail" as you
suggested. I get the same problem.

>2. Check panic log for any clues


The panic log says nothing. If I kill clamd, there are messages in
the panic log saying that it can't connect to clamd...otherwise
nothing.

clamav's log is also not helpful....I thought having "verbose"
logging would tell me something, but it doesn't seem to. It logs
when a virus is successfully detected (like when I tell it SCAN
/path/to/virus), it logs when it does it's self checks, and it logs
the fact that it started and stopped.

I wish the problem was really that easy...I'd have it running already.
