[Exim] Callout question

I just started using callout for sender verification with exim 4.12. I'm
seeing this every so often:

2003-01-03 12:24:11 H=(mail.atexe.net) [67.98.243.22] sender verify
defer for <Craig220498@???>: response to "initial connection" from
mail.oska.net [66.230.223.92] was

Now, I know this is spam and all, but it just seems like this isn't
quite correct as far as logging goes. A telnet to 66.230.223.92:25 gives
a connection refused. Shouldn't exim log it as such?

Thanks,

Paul
