for security reason (and for other reasons too) I want to hide “Postfix” from SMTP response
[[email protected] ~]# telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 mail.example.biz ESMTP Postfix
I need the answer to be only:
220 mail.example.biz ESMTP
Is this possible?
smtpd_banner. Note that per protocol,
$myhostname must be the first argument.
smtpd_banner = $myhostname ESMTP random mail server bent over and ready.
