Smtp auth

When I upgrade to Hardy Heron, it looks like I'll have an easier time getting mail to work.

Here is an Ubuntu-specific recipe that looks like it will do the job:

https://help.ubuntu.com/7.04/server/C/postfix.html

Currently, my mail service is working as long as I don't try to send mail from a remote machine. For instance, if I have a laptop configured to send mail outgoing mail to my server and am connecting through an untrusted network in a coffee shop or a friend's house, I am unable to connect to the server. This must be fixed.

There are several differences between my existing /etc/postfix/main.cf config and the recipe linked above:

Current	Proposed
smtpd_sasl2_auth_enable = yes	smtp_sasl2_auth_enable = yes
smtpd_sasl_local_domain = finninday.net	smtpd_sasl_local_domain =
	broken_sasl_auth_clients = yes
	smtp_use_tls = yes
	smtp_tls_note_starttls_offer = yes
