I have been using postfix for about two + years but something that was
just out of my understanding at the time was setting up relaying.
Right now I just sent from my mail client (thunderbird) but I would
like to be able to send back through postfix to keep a record of all
sent mails.
Im getting this error:
postfix/smtp[18963]:

sm...@smart-laptop:~$ postconf -n

relayhost = 72.167.82.80:465
(side note, the IP should be enclosed in brackets,
relayhost = [72.167.82.80]:port
but that's probably unrelated to this problem.)
Using port 465 implies that the client is expecting
wrapper-mode TLS. This mode is deprecated for email use and
not directly supported by postfix.
The vast majority of mail relays also support using the
standard "submission" interface at port 587, which is the
strongly preferred port.
If it's an antique mail relay that doesn't support the
submission port, a workaround for client side wrapper mode is
described here:
