The smtp_server process which handles incoming email, has this error when the akismet filter is enabled. There may be a similar issue with mollom spam filtering (I haven't checked).
smtp_server apparently doesn't set up a full (fake) web task like taskd does. But in this situation a different IP addr should be used anyway (try to find bottom-most non-internal IP address in Received headers?)
