  An alternative is to have smmsp forward directly to a relay host.
Then you only need to run smmsp (the queue runner, in case any mail
gets queued for some reason), and no local smtp daemon is needed.
To do this, add to your .mc file for smmsp the line:

  FEATURE(`msp', `[relayhost]')dnl

instead of the usual:

  FEATURE(`msp')dnl

where "relayhost" is replaced by the name of your relay.
