HowTos/SMTP Greeting
From Scalix Wiki
When you telnet onto the Scalix Mailserver on Port 25, you are given the standard Scalix greeting:
220 mail.yourdomain.net ESMTP Scalix SMTP Relay 10.0.1.3; Mon, 07 Aug 2006 17:28:04 +0100 (BST)
This gives away quite a bit of information (including the fact that you are running Sendmail, therefore this should be changed to something less descriptive.
Edit /var/opt/scalix/sys/smtpd.cfg, add:
GREETING=SMTPD;
Underneath "EXTENSIONS="
Once you've made your edits, restart the Scalix SMTP Daemon:
omoff -d0 smtpd omon smtpd
