Add another ~2MB resident if you also have tlsmgr running.  :-)  But yes, 
Postfix strikes me as very lightweight compared to most alternative MTAs.

I used to expect to need to administer sendmail on every Unix box I dealt with. 
 And I can deal with keeping 100+ Unix boxes continually updated with the 
latest sendmail patch and M4-macro generated config update, but I'm 
considerably happier with the notion of dealing with Postfix more often than 
sendmail.

It seems reasonable to ship an MTA with the base system, which is by default 
configured off-- or possibly, configured for listening on localhost:25 for 
local delivery only.
