I'm trying to set up a simple email relay host, with my home
linux box sending to smtp.indra.com.
I'm running Postfix 2.9.6-1~12.1 on Xubuntu,
and I need to use SSL to talk to indra.

I think SSL works on port 465 because I can use openssl to connect:

openssl s_client -crlf -connect smtp.indra.com:465
334 VXNlcm5hbWU6     # base64 prompt for "Userid:"
(send my base64 userid)
334 UGFzc3dvcmQ6     # base64 prompt for "Password:"
(send my base64 password)
235 2.0.0 OK Authenticated

I tried to do this in postfix, by using
    relayhost = smtp.indra.com:465
    smtp_sasl_auth_enable = yes
    smtp_sasl_mechanism_filter = login
    smtp_sasl_password_maps = hash:/etc/postfix/sasl/passwd
    [smtp.indra.com]:465 myUserName:myPasswd
  postmap sasl/passwd
  service postfix restart

I get:
  Mar 28 14:22:02 helix postfix/smtp[10392]: CLIENT wrappermode (port
smtps/465) is unimplemented
  Mar 28 14:22:02 helix postfix/smtp[10392]: instead, send to (port
submission/587) with STARTTLS

When I change to the port from 465 to 587 in the above 2 files
and restart postfix, I get:

Mar 28 14:25:47 helix postfix/smtp[10568]: C539F1822CD:
to=<someone at indra.com>, relay=smtp.indra.com[]:587, delay=7.1,
delays=0.09/0/6.8/0.15, dsn=4.7.1, status=SOFTBOUNCE (host
smtp.indra.com[] said: 550 5.7.1 <someone at indra.com>... Access
denied (in reply to RCPT TO command))

Any thoughts?

Many thanks,
