Sam,
Is there a way to get spamdyke to log invalid authorizations in a manner
that fail2ban can use? My host has been hit continuously with
brute-force attacks. Unfortunately, the logs only have:

They seem to have a huge list of account names to try and I've got
thousands of attempts just for today. Unfortunately, without any IP
address in the message I can't have fail2ban automatically block these.
