[exim] log_message and drop?

Does log_message not work with drop?

This produces a log message

defer    log_message = REJECTED - Spammer Connected to FAKE highest MX 
record VIRUS Brown - I=$interface_address
    dnslists = hostkarma.junkemailfilter.com=127.0.0.4

This does not.

drop    log_message = REJECTED - Spammer Connected to FAKE highest MX 
record VIRUS Brown - I=$interface_address
    dnslists = hostkarma.junkemailfilter.com=127.0.0.4
