Since the smtpd_banner is not in the main.cf file it should assume the Postfix default, which is "$myhostname ESMTP $mail_name". I'm guessing that changing the $myhostname variable didn't work because it repopulated that value when you restarted, probably from the localconfig.xml file. I would think if you manually added the smtpd_banner variable to the main.cf file it would work, but again not sure about surviving an upgrade. |
