Hi Hope someone can help,
It appears that root and amavis are trying to send mail to root (alias postmaster) but this is being bounced. All users are present when cat /etc/passwd.
How can I fix this bouncing?
System otherwise works perfectly. mail can be received and sent internally and externally by roundcube users.
Many thanks

Re: bounced system mail

You can create an alias for system accounts (amavisd and root user in your case) in Postfix (/etc/postfix/aliases), then all emails sent to them will be sent to the alias account. For example:

# File: /etc/postfix/aliases
amavisd: postmaster@my_domain.com

After updated this file, please execute below command to make it work:

# postalias /etc/postfix/aliases
