NethServer Version: 7.4.1708 (beta1)
Module: email / postfix
After upgrading to Nethserver 7.4.1708, I get an error when sending email to another Nethserver …
Example: Error Message of return mail –
emailuser@domain Host or domain name not found. Name service error for
name=xxx.1xx.xx.xxx.domain type=AAAA: Host not found
why is it looking for a IP6V Address for the other Mail Server… ?
when doing nslookup … it shows that the domain is set with an IP4V on the receiving email server…not IP6V
My Email Server is using ip4V, no ip6V , yet the nethserver postfix seems want to send email using ip6V…
Is there a setting that I missed that I can default my Nethserver POSTFIX to send EMAILS via IP4V address ?
