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. On 01/31/2013 01:04 PM, Michael D. Sofka wrote: > I would like to see this too.

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.
