This is very much nearly what I got to. Note though that outbound port
25 is blocked, but my smarthost listens on the submission port as well
if auth is used. So my relayhost line says:
relayhost=my.smarthost.com:587
On my relayhost maillog I can see the connection appears, but mails are
bounced with:
530 5.7.0 Authentication required (in reply to MAIL FROM command)
$ cat /etc/postfix/relay_password
your.smarthost.com yourusername:yourpassword
I have tried
my.smarthost.com username:password
and
[my.smarthost.com]:587 username:password
and
my.smarthost.com:587 username:password
With various entries in main.cf to co-incide with these... (and
remembering to run postmap each time).
$ postmap /etc/postfix/relay_password
$ service postfix reload
You can check out the commented option in the man pages or
http://www.postfix.org/postconf.5.html
if you're interested later/have some spare time/if it doesn't work ;-)
The line I get in the logs on my smarthost is:
Jan 11 18:31:35 gate sendmail[17441]: STARTTLS=server,
relay=188.29.xxx.xxx.threembb.co.uk [188.29.xxx.xxx],
version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-SHA, bits=256/256
The mail just bounces back to the sender, nothing else on the smarthost
logs.
