Re: Restrict access to a single client device

You use SMTP authentication through postfix or sendmail.  Google [ mail 
authentication relay   ] and you should find lots of howtos.

I'm setting it up to use a sasldb to authenticate external users in 
order to keep them apart from UNIX users.  Be very certain that you use 
STARTTLS or some form of authentication for email.  Also, if you're 
allowing internet access to e-mail, you'll want to use imaps or https.

-- 
There is a greater darkness than the one we fight. It is the darkness of 
the soul that has lost its way. The war we fight is not against powers 
and principalities, it is against chaos and despair. Greater than the 
death of flesh is the death of hope, the death of dreams. Against this 
peril we can never surrender. The future is all around us, waiting in 
moments of transition, to be born in moments of revelation. No one knows 
the shape of that future, or where it will take us. We know only that it 
is always born in pain. G'Kar
