[BC] Internet blackmail or stupidity? Barracuda users, especially, note!

[Robert Meuser]

I am on numerous Yahoo groups. My outbound SMTP server is always 
Outbound Mailhop at DYNDNS. My incoming is is DYDNS mail forward via my 
registered domain. The messages go to various end mailboxes and 
originate from various devices and services and Yahoo has never 
complained. All my mail accounts have reply to addresses.
