Hello.!
I update the version of my postfix server:
[root@vps-1713830-x /etc/postfix] # postconf mail_version
mail_version = 3.4.7
I set a round-robin map in the main.cf and enable ipv6 support:
[root@vps-1713830-x /etc/postfix] # postconf -d|grep inet_protocols
inet_protocols = all
lmtp_balance_inet_protocols = yes
smtp_balance_inet_protocols = yes
In the master.cf i set this:
smht38-165<---->unix - - n - - smtp
-o smtp_bind_address=IPv4
-o smtp_helo_name=smht-relay01.hostname.tld
-o syslog_name=smht-relay01
relayipv6<----->unix - - n - - smtp
-o smtp_bind_address=IPv6
-o smtp_helo_name=relayipv6.hostname.tld
-o syslog_name=relayipv6
When I send an email, the ipv4 address where the ipv6 interface is
configured appears in the received header, and I see this message
2020-02-11 12:05:06 1j1X5y-0000BS-SQ <= r...@vps-1713830-x.hostname.tld
H=hostnameipv4.hostname.tld (relayipv6.hostname.tld) [ipv4] P=esmtps
X=TLS1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no S=1513

"warning: smtp_connect_addr: bind 2800:6c0:3::xxxx Address family not
supported by protocol"
Another question, is it possible to configure several round-robin maps
for different IP addresses?
Example:
smtpd_sender_restrictions = check_client_access
hash:/etc/postfix/client_ip hash:/etc/postfix/client_ip2
client_ip ==> round-robin map massive
cliente_ip2 ==> round-robin map transactional
This is to divide those users who send bulk with transactional emails.
Regards!!
