Hi
As of today, i'm receiving multiple alerts:
Directory Harvest Attack : [ domain ] Default Email Config 1
Action: block '550 mailbox unavailable'
with various sources.
What does this mean - and what to do about it?
Thanx in advance,
HBE

These are Connection Manager alerts telling you Postini is doing its
job, which is preventing spammers from harvesting valid email
addresses off of your server, i.e., Direct Harvest Attack (DHA). Your
server will send back receipt SMTP errors for non-existent accounts.
Where there is an unusual amount of requests from an IP, Postini will
shut it down reducing server loads. Your Admin guided has further
information under the section, Connection Manager.
