postfix welcome message smtpd_banner

Question

I would like to greet the remote client showing his IP.

For example:

"mysite.com ESMTP Hello xxx.xxx.xxx.xxx your actions will be logged"

I have this...

smtpd_banner = $myhostname ESMTP Hello $client_address your actions will be logged

But $client_address is not showing the remote client IP. What variable should I use in order to show the client IP? how can I accomplish what I want to do?

You can do this with exim smtp_banner = "$smtp_active_hostname, ESMTP Hello $sender_host_address your actions will be logged" — ALex_hha, Jul 24 '13 at 20:59

It's not possible, in the smtpd_banner you can use only 2 variables - $myhostname and $mail_name
