make it part of your overall services and policy, that you require a
list of authorized users .. if you dont know about joe@your-customer.com
than you will consider it a forged acct
- you now have a list of all valid email accounts and
any unknown address is rejected/bounced/fried/devnulled
( the users does NOT have to have a shell acct ...
( gazillion ways to do this
- you reject unknown users on incoming email addressed to joe
- you reject outgoing mail from "joe"
( ez to do with wireless laptops )
- and if joe is using a borrowed laptop from the spouse
or sitting at a different office pc ... humm .. more isssues
> Bounce.
