Scanning to email and status updates don't require a server as such, and 
in the interests of security they generally don't.

What I have noted before (despite my brainfart on 9100, excuse me; I was 
sure I had known it by another name) is that IF the machine is 
multifunction and can fax, then it would need a smtp server to email to 
fax. To do this it needs to _receive_ email, not just send. There is 
usually a driver utility that knows how to speak to it though, but it 
should be easy to hack.

As evidence I checked my printer and it can send email status messages 
and has no smtp server. Telnet is normal (it is usually secured and used 
by a qualified technician), and is used to configure other options and 
nvram settings that may not be available on the menu.
