Good day Everyone. I have been getting this error in the postfix syslog for the past 3 days and have been searching for the solution since.
Now, I have replaced that email address with my main email address from gmail because I thought maybe using duck.com is not accepted in PBS.I am still getting the error in the syslog.
I have put in my gmail email address in Configuration >> Other
I also made sure it was entered in Email section within the user option under Access Control>>>user management.
I also looked under /etc/postfix/main.cf but didnt see the duck.com email address.
Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

myhostname=pbs.mydomain.com

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 = $myhostname, localhost.$mydomain, localhost
relayhost =
mynetworks = 127.0.0.0/8
inet_interfaces = loopback-only
recipient_delimiter = +

compatibility_level = 2


Can anybody help me figure out where it could be still lingering in the config somewhere?
PBS info:
client version: 3.0.4

Hi!
I think your config did not get reloaded correctly... Did you execute: postfix reload ? You could also try postfix check to check that all configurations have been applied correctly.
The documentation is here: http://www.postfix.org/BASIC_CONFIGURATION_README.html
Thank you . I managed to fix it by setting up a sasl_passwd file. I had thought pbs would use the proxmox node email settings since it was a vm in the same host.
all is good thanks.
