Internode has recently stopped accepting outgoing email on port 25, with a switch to SMTPS on port 465.
(Found out after outgoing mail was blocked by their mail sevrer, and their helpdesk sent a link to related info.)

Though I'd prefer proper postconf commands, the only related postfix config info I've found on the intertubes is a
direct edit of /etc/postfix/master.cf to uncomment the SMTPS lines:

   #smtps     inet  n       -       -       -       -       smtpd
   #  -o syslog_name=postfix/smtps
   #  -o smtpd_tls_wrappermode=yes
   #  -o smtpd_sasl_auth_enable=yes
   #  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
   #  -o milter_macro_daemon_name=ORIGINATING

A quick check of /etc/services shows we already have:
   ssmtp           465/tcp         smtps           # SMTP over SSL

So after a "postfix reload", outgoing mail was  ...  still rejected by mail.internode.on.net

Hmmm, a "postconf | more"  showed:        default_transport = smtp

so I commented out the SMTP line in /etc/postfix/master.cf :

smtp      inet  n       -       -       -       -       smtpd

Another "postfix reload", and outgoing mail is  ...  still rejected by mail.internode.on.net

The question now is what am I missing? (I'm most reluctant to blow postfix away and start figuring out how to make
mutt talk SMTPS by itself. At least I have a history of good experiences with postfix MTA.)

(Using webmail for the first time. Why does it paste at mouse, not at text cursor?? That's awful.)
