configuring a relay server with postfix

borrougagnou

Hello,
I have a problem, I try to configure a mail relay server with my vivaldi email and postfix

but I'm blocked with different message and error
and I would like to know what configuration I missed or what is the exact problem...

this is my /etc/postfix/main.cf

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

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 = domain.ext
relayhost = [smtp.vivaldi.net]:587
inet_interfaces = loopback-only
recipient_delimiter =

# 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/sasl_passwd
# Enable STARTTLS encryption
smtp_use_tls = yes
# where to find CA certificates
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

smtp_sasl_mechanism_filter = plain, login
smtp_tls_security_level = encrypt

myorigin = /etc/mailname
mailbox_size_limit = 0
inet_protocols = all
compatibility_level = 2
mynetworks = 127.0.0.1/32 [::1]/128

and I obtain error like:

@borrougagnou said in configuring a relay server with postfix:

553 5.7.1 [email protected]: Sender address rejected: not owned by user [email protected] (in reply to RCPT TO command)

In this case, although you have successfully authenticated, you are trying to relay a mail from a mail address that does not match that of your account. This is not allowed.

@thomasp Hi, thank you for your answer
what do you mean by " a mail address that does not match that of your account"

I try to match both of thing

if you check the log, I send 2 log, I just done few modification like add my vivaldi email directly into postfix, than the email adress from my own server.

maybe I done a bad configuration ? where is my error ?

edit:
username = my vivaldi account name

@borrougagnou As can be seen in the error message, the sender address is [email protected], not [email protected]

IT WORK !!! finally it work after IDK how many year !!!
if someone have this problem too, I recommend to follow this tutorial about changing "root@server" by "[email protected]" :

https://www.ollegustafsson.com/en/postfix-fix-wrong-sender-address/
it's about create a "sender_canonical_maps"

also thank you to @thomasp for showing me my mistake.
