In the security log I found about 100 of these entries in less than 3 hours (about 8pm to 11pm Los Angeles time)

[25/Apr/2012 20:53:21] SMTP: Invalid password for user user<_at_>mydomain.com. Attempt from IP address 183.7.122.235.
[25/Apr/2012 20:53:27] Failed SMTP login from 183.7.122.235

An iplookup showed this to be a Chinese IP but it does not appear on any spam lists.

Am I wrong or is this someone trying to hack into this user's mail account? I don't see where I can tell KC to alert me about this kind of suspcious activity or tell it to block such repeated attempts (say after 5 or 10 tries, and mark/block this IP address). This may be a feature to ask for?
