relayhost = [smtp.gmail.com]:587

1. make sure there are these packages
# dpkg -l | grep sasl
ii libsasl2-2:amd64 2.1.25.dfsg1-6+deb7u1 amd64 Cyrus SASL - authentication abstraction library
ii libsasl2-modules:amd64 2.1.25.dfsg1-6+deb7u1 amd64 Cyrus SASL - pluggable authentication modules

2. add to /etc/postfix/main.cf
Code: 
smtp_sender_dependent_authentication = yes
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost.hash

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_auth.hash
smtp_sasl_security_options = noplaintext, noanonymous

smtp_use_tls = yes
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

3.in /etc/postfix/sasl_auth.hash:
Code: 
<servername>:587 <login>:<password>
with gmail it's
Code: 
smtp.gmai.com:587 yourmail@gmail.com:<password>

in /etc/postfix/sender_relayhost.hash
Code: 
<sender email address> <smtp-server>:587
<sender email address> in my case is root@pve.example.com, it's important to be FQDN for certain mail servers to accept mail from.
with gmail, its reasonably to use yourmail@gmail.com, like
Code: 
yourmail@gmai.com smtp.gmail.com:587


then
Code: 
postmap /etc/postfix/sasl_auth.hash
postmap /etc/postfix/sender_relayhost.hash
postfix reload

4. test it
e.g.
Code: 
date | mail -s test yourmail@gmail.com

yes, my proxmox send notifications using SASL-authentication to server on 587 port.

probably your problem is with TLS.
try turn it off with
smtp_use_tls = no
to debug prove it.
 
sorry, forgot to mention, I did with
Code: 
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost.hash
with commented out
Code: 
#relayhost =
in /etc/postfix/sender_relayhost.hash
Code: 
<yourmail>@gmail.com smtp.gmail.com:587
and
Code: 
postmap /etc/postfix/sender_relayhost.hash && postfix reload

try test and the same problems
 
notifications backups

when configuring backups thereis popdown menu with options
- always
- on failure only.

in datacenter-options thereis
Email from address

you need to change it to what is in postfix config, i.e. tsistemas@gmail.com

manual backups, no sheduled

PVE has an option for email address to sent notifications from.
you need to adjust it to the one configured in postfix sender_relayhost options, that is to yourmail@gmail.com.

otherwise PVE is using its standard root@$hostname, which doesn't fit to postfix config and remains unsent.

btw, check /var/log/mail.log

yes, it was unattentioned advice, a mistake.

find and comment out the option in postfix main.cf where "/etc/postfix/sasl_auth.hash" is mentioned. it's not necessary now.
