I've found Fridays are a particularly popular day. One odd thing we've noticed sinced implementing IMGate is the number of viruses getting through has been reduced (and I turned off all extension filtering in Postfix so .exe, .pif and the like get through). I suspect that at least some of these dictionary attacks are being mounted for the purpose of spreading worms. -- A.
