[Dshield] SMTP server banner?

Hello,

When configuring an SMTP MTA for an external mail gateway, are there
any best practices in terms of what the banner should display?  For
example sendmail by default tells you sendmail is running and the
version.  I don't like that.

So my initial thought is maybe just the machine name they connected to
(our public mx record).  But are there any RFC or general requirements
that we display anything in particular?

Thanks
Shane
