--portport, -p port
              Binds to a specific port, instead of the default 2525.

       --useruser, -u user
              On startup, switch to run as user instead of the starting user.  Applies only when started as root
              (as is normal when listening on port 25).

       --limit-connectionslimit, -c limit
              Accept  at  most  limit  simultaneous  connections.   Inbound connections beyondthis limit will be
              deferred or refused.

       --max-from-iplimit, -m limit
              Accept at most limit simultaneous connections  from  any  given  IP  address;  does  not  override
              --limit-connections, if set.

       --listen-addressaddr, -l addr
              Bind to the local address addr, instead of the default behavior of binding to all interfaces.  Can
              be specified multiple times to bind to more than one interface or local address.

       --detach,-d
              Detach  from  the controlling terminal at startup, to run as a standalone daemon.  See also --pid-file.

       --pid-filefilename
              Upon startup, and after daemonizing if applicable, write the process ID to filename,  for  use  by
              sysvinit control scripts or similar utilities.
