I have configured postfix on RHEL 6.4 and I can connect to postfix on 25 port but no banners return and ehlo doesn't work either.

I have uncommented the smtpd_banner line and here it how looks.

smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)

My hostname returns my server's FQDN postfix.labp.com

Postfix is listening on all IPs on port 25.

I didn't touch the master.cf file and it looks configured properly or so I have noticed from other posts. I'm unable to find the culprit.

I would appreciate any help.

Thanks Mo
