Postfix multi IP/Domain SMTP Helo'ing

We have Postfix running with two domain and each domain has own IP so it's isolated.

But Spamhuaus blocked my IP and saying you are sending "localhost.localdomain" HELO

I am already using smtp_helo_name SMTP option

How do i tell my postfix send specific domain related HELO when sending email? I have following config in master.conf

#smtp      inet  n       -       n       -       -       smtpd
127.0.0.1:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-localhost
      -o smtp_helo_name=localhost
      -o smtp_bind_address=127.0.0.1
      -o myhostname=localhost

65.xxx.xxx.100:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-mail.abc.com
      -o smtp_helo_name=mail.abc.com
      -o smtp_bind_address=65.xxx.xxx.100
      -o myhostname=mail.abc.com

65.xxx.xxx.200:smtp inet  n     -       n       -       -       smtpd
      -o syslog_name=postfix-mail.xyz.com
      -o smtp_helo_name=mail.zyx.com
      -o smtp_bind_address=65.xxx.xxx.200
      -o myhostname=mail.xyz.com

abc-out  unix -       -       n       -       -       smtp
   -o smtp_bind_address=65.xxx.xxx.100
   -o smtp_helo_name=mail.abc.com
   -o syslog_name=postfix-mail.abc.com

xyz-out  unix -       -       n       -       -       smtp
