[SOLVED] Postfix configuration with a smtp.office365.com smtp server for sending email only

[willis]

Hi,

I try to configure Postfix on Proxmox 6.1 to send "backup or smart notifications" to my "Microsoft account".

When I try : << echo "text du message1" | mail -a "From: myaddress@live.fr" -s "test 2" myaddress@live.fr >>
it's ok, I receive the mail

But When I try :
echo "text du message1" | mail -s "test 2" myaddress@live.fr
I don't have any issue but I don't receive the mail.

What's wrong in my configuration ?

My conf:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

myhostname=mypc.mylocaldomain

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = $myhostname, mypc.mylocaldomain, localhost.mylocaldomain, localhost
relayhost = [smtp.office365.com]:587
inet_interfaces = all
recipient_delimiter = +

compatibility_level = 2

myorigin = /etc/mailname
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
inet_protocols = all

# enable SASL authentication
smtp_sasl_auth_enable = yes
# disallow methods that allow anonymous authentication.
smtp_sasl_security_options = noanonymous
# where to find sasl_passwd
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
# Enable STARTTLS encryption
smtp_use_tls = yes
# where to find CA certificates
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

And the "/etc/mailname" is :
mypc.mylocaldomain

Thank you in advance for your help.

Hi, sorry for this stupid "question".
I found my listake.
Hope it will help others : I forgot to configure "Datacenter/option/Sender email". After that it's ok.
