    Before you save changes, add the following lines at the bottom of the file:

    [[email protected] conf.d]# postfix check
    /usr/sbin/postconf: fatal: file /etc/postfix/ line 129: bad field count

      Go the line 129 in file and check for any extra spaces or use correct spacing..

      dovecot   unix  -       n       n       -       -       pipe
      flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}

    Hello Gabriel A. Cánepa,

    Me too have the same issue, Please comment on this. I have doubt the path “argv=/usr/libexec/dovecot/deliver” in line 134. Is it matching with your tutorial ? Actually that line needs a bit explanation, please consider. thanking you in advance….

    /usr/sbin/postconf: fatal: file /etc/postfix/ line 134: bad field count
    postfix/postlog: warning: inet_protocols: disabling IPv6 name/address support: Address family not supported by protocol
    postfix/postfix-script: fatal: cannot execute /usr/sbin/postconf!
