Rob,

Several of my hosted clients are ex-Servlets.com users; I'll leave it be at
that.  I've never used Servlets.com, but my clients have their reasons.

As a practical matter, there are few hosts whose e-mail servers are
obfuscated.  There is really little point.  It isn't as if it is hard to
find out what they are using via other means.  And the automated scanners
just try various vulnerabilities regardless.  We see that all the time with
various Internet applications.  As cryptographers would tell you, security
by obscurity is not a particularly secure approach:

I'll leave you to browse the other 76,000+ references from Google.  ;-)

LOL  The name is apt, but I don't see the feature on that page.

Sendmail is a completely different beast from James.  Sendmail wants
privileged access, James doesn't.  Sendmail has buffer overflow issues.
James doesn't.  Etc.  James does not need or want any special permissions
other than to access the ports.  You can easily run James as a normal user
using just:

   $ iptables -t nat -A PREROUTING -p tcp --dport smtp -j
REDIRECT --to-ports 10025
   $ iptables -t nat -A PREROUTING -p tcp --dport pop3 -j
REDIRECT --to-ports 10026

and changing the ports in config.xml.
