Customer-facing ACLs

Hi Justin (and all others on-list)

I understand your grounds for blocking outbound SMTP for your customers 
(especially those on dynamic IP connections).
It probably will do good to block infected customers that are spewing 
spam all over the world.

However, considering the number of mobile workers out there who send 
email via their laptops to corporate SMTP servers, won't blocking 
outbound SMTP affect them?

Since these corporate types (I'm guessing here) are probably unaware of 
how to change their email client's SMTP configurations, chances are that 
blocking outbound SMTP will probably cause quite a lot of pain.

After all, there are also those who frequently move from place to place 
so they're going to have to keep changing SMTP servers every time they 
go to a new place that's on a different ISP.

Cheers
