Relay access denied... #5
Description
When I send mail using ssmtp server and postfix in docker as a mailhub then I got an error like relay access denied.
My /etc/postfix/main.cf file is as follows:-
See /usr/share/postfix/main.cf.dist for a commented, more complete version
Debian specific: Specifying a file name will cause the first
line of that file to be used as the name. The Debian default
is /etc/mailname.
myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
appending .domain is the MUA's job.
append_dot_mydomain = no
Uncomment the next line to generate "delayed mail" warnings
