Reverse DNS does not match SMTP banner

[curibe]

how do i change SMTP banner on EFA??

[zohman]

very good practice!

search for smtpd_banner in /etc/postfix/main.cf

Code: Select all

smtpd_banner = mail.example.com ESMTP Mail Service Ready

change mail.example.com to your ptr(rDNS),
restart\reload postfix for the changes to take effect,

Zohman.
